ST 352 Continue until all p-values are less than.05.  The variables left are the significant predictors of the response variable and the regression equation should be formed from model that includes only these explanatory variables. :  the percentage of the variation in the response variable that is explained by the regression on the explanatory variables. If the null hypothesis is not rejected, stop the analysis!!!  None of the explanatory variables are useful in predicting the response, so there is no need to continue. oregonstate.edu /instruct/st352/kollath/handouts/multiplereg/multipleregsteps.htm   (643 words)

Technical Brief on the Statistical Model The correlation between the response variables and the explanatory variables is shown in Table 2. The study of multiple explanatory variables interacting simultaneously to produce the outcome on one or many response variables is termed Multivariate Analysis. In the statistical model it is our intention to present the significant causal connection between a set of explanatory variables and a response variable. www.infoworks.ride.uri.edu /2002/techbrief/appendix-A.asp   (1837 words)

quiz4sol It is the potential for the confounding variable to cause changes in the response that presents difficulties. "The results" of the study are changes in the response variable. If the treatment groups differ on a third, confounding variable, observed difference in the reponse may be due to the confounding variable and not the explanatory variable. www.ms.uky.edu /~viele/sta200f98/quiz4sol   (392 words)

Analyzing Patterns of Missing Data the diagnostic variable name for "response" would be "respon_1" if we had already used the name "respons_" for a diagnostic variable. the diagnostic variable name for "response" would be "respons_". To determine whether or not the pattern of missing data is random, we create a special diagnostic variable that indicates whether the variable is missing or valid for each case in the data set. www.utexas.edu /courses/schwab/sw388r7/Tutorials/Analyzing_Patterns_of_Missing_Data_doc_html/010_Creating_Dichotomous_Valid_Missing_Variables_for_Diagnosing_Missing_Data.html   (375 words)

Classics in the History of Psychology -- MacCorquodale & Meehl (1948) This equation asserts that habit strength is a certain joint function of four variables which refer to direct empirical quantities-number of reinforcements, delay in reinforcement, amount of reinforcement, and asynchronism between the discriminative stimuli and the response. We propose a linguistic convention in the interest of clarity: that the phrase intervening variable be restricted to concepts of the first kind, in harmony with Tolman's original definition; and that the phrase hypothetical construct be used for those of the second kind. These hypothetical constructs, unlike intervening variables, are inadmissible because they require the existence of entities and the occurrence of processes which cannot be seriously believed because of other knowledge. psychclassics.yorku.ca /MacMeehl/hypcon-intvar.htm   (375 words)

Educational Psychology Interactive: Operant Conditioning Notice that the number of responses per time period increases as the schedule of reinforcement is changed from fixed interval to variable interval and from fixed ratio to variable ratio. Variable interval -- the first correct response after a set amount of time has passed is reinforced. This connection causes the probability of the response to change (i.e., learning occurs.) chiron.valdosta.edu /whuitt/col/behsys/operant.html   (1628 words)

Article - Virginia - SoftSolutions, Inc. However, low control variable (used to control the process) to response variable (being measured) correlation can mask the time it appears to take for a process change to be implemented. Indeterminate measurements (statistical) may also require consideration of response-to-control (RtC) variable correlation and autocorrelation. When indeterminate measurements are taken at a slower rate than the time it takes for process changes to be fully implemented then measurement adequacy is not an issue. www.softsolutionsit.com /news/articles/CharacterizingProcess.html   (1628 words)

Modeling of electrostatic microactuators The static response to a dc voltage is first determined to investigate the influence of varying the geometric parameters of the device on the range of travel and pull-in voltage. The dynamic response of the microbeam to a dc voltage is also determined for various distributions of the microbeam width and thickness and the gap size. An increase (decrease) in the gap size at the middle with respect to those at the endpoints results in an increase (decrease) in the pull-in voltage and an insignificant effect on the range of travel. stacks.iop.org /0960-1317/15/419   (407 words)

EconPapers: Indicator Variables for Optimal Policy Abstract: The optimal weights on indicators in models with partial information about the state of the economy and forward-looking variables are derived and interpreted, both for equilibria under discretion and under commitment. The optimal response to the optimal estimate of potential output displays certainty-equivalence, whereas the optimal response to the imperfect observation of output depends on the noise in this observation.

VII As knowledge of these fields and the corresponding atmospheric response increases, they may be also become prognostic variables. Of these fields, the land surface temperature, sea ice temperature, and snow depth vary so quickly with time that they are treated as prognostic variables in the model and are coupled with the atmospheric equations. The snow depth is applied as an initial condition, and carried as a prognostic variable in the model (see section IIIB). grads.iges.org /agcm/agcm_bound.html   (1940 words)

WaveWarp Component Library-- Spectrum Analysers-- Frequency Response Analyser It is assumed that the "Input" variable in the "transfer function" is the first audio input, and the "Output" variable is the second audio input, such that the frequency response is given by "Ouput divided by Input" i.e. Note: this component is useful for characterising the frequency response of single or multiply-connected components (filters or otherwise!). The frequency response is computed by dividing, point-by-point, the computed spectra of the two inputs. www.soundslogical.com /support/wavewarp/documentation/english/documentparts/Frequency_Response_Analyser.html   (1940 words)

Coefficient of determination - Wikipedia, the free encyclopedia is the proportion of a sample variance of a response variable that is "explained" by the predictor variables when a linear regression is done. is the square of the correlation between the predictor and response variables. the independent variables are a true cause of the changes in the dependent variable en.wikipedia.org /wiki/Coefficient_of_determination   (216 words)

EE213_SS2.doc The impulse response is the response of the circuit in zero state to an input that is an impulse. The step response is the zero state response of the circuit to an input step and the natural response is the response of the circuit in zero state to an input that is a time reversed unit step: the input is unity for negative times and zero for positive times. To obtain the state transition equation, the capacitor is replaced with a pseudo voltage source of value x(t), since the state variable is a "known" quantity in the state transition equation. www2.hawaii.edu /~allencha/EE213_SS2.doc   (3829 words)

DictL24.html ] Physical quantities used in photometry, such as luminous intensity and luminance, which are based on the response of the human eye, and are thus weighted to take into account the difference in response at different wavelengths of light. ] The unit of luminous flux, equal to the luminous flux emitted within a unit solid angle (1 steradian) from a point source having a uniform intensity of 1 candela, or to the luminous flux received on a unit surface, all points of which are at a unit distance from such a source. ] The ratio of luminous flux in lumens emitted by a source at a particular wavelength to the corresponding radiant flux in watts at the same wavelength; thus this is a measure of the visual sensitivity of the eye. www.accessscience.com /Dictionary/L/L24/DictL24.html   (2348 words)

A Filter Primer - Maxim/Dallas A type of filter that is common to many applications requires a response that is flat in the passband but cuts off as sharply as possible afterwards. The double zero at infinite frequency goes to zero frequency, and the finite response at zero frequency becomes infinite. Note that all the filters described have the same number of zeros as poles (this must be the case, or the transfer function would not be a dimensionless expression). dbserv.maxim-ic.com /tarticle/view_article.cfm?article_id=117   (2348 words)

krohn Test Equipment sales and rentals at Test Equipment Connection Variable Dual Channel Electronic Filter The 3322 Variable Dual Channel Electronic Filter is an all solid state, variable electronic filter that is digitally tuned over the range from 0.001Hz to 99.9kHz in six bands. The frequency response characteristic of the unit is a fourth-order Butterworth with maximum flatness for cleanest filtering in the frequency domain. For pulse or transient signal filtering, a front panel switch is provided to change the frequency response to RC optimum for transient-free filtering. www.testequipmentconnection.com /manu-search.asp?smanufacturer=krohn   (2348 words)

Lifestyles Therapeutics The response achieved varied with temperature attained and a minimum temperature of 40 degrees C for 40 minutes produced the greatest number of responses. Response to hyperthermia was directly related to the temperature achieved and the length of time the temperature was applied.

glsvlsi,Great Lakes Symposium on VLSI '98 The stability of a continuous-time state variable filter is analyzed using the Routh-Hurwitz criterion. The filter is examined separately with integrators implemented with an op-amp and an OTA-C. Both amplifier types are characterized by a dominant-pole frequency response, and the stability of each implementation is compared. Since the analyses assume a dominant-pole response, all higher-order poles of the actual amplifier must also be much greater than the unity-gain frequency to minimize excess phase. doi.ieeecomputersociety.org /10.1109/GLSV.1998.665203   (414 words)

State-variable filter problem......... I am trying to build a state-variable audio filter and it simply just doesnt work as it should, by changing R3 and R4 it suppose to change the cut off frequency but I've simulated and built it on the breadboard they both seems to get the same result. The problem is that the HP, LP and BP don't seem to appear displaying the right shape of response, the value I have in the circuit should cut off at 15hz. Bandpass don't appears to work as bandpass and highpass don't work as highpass, well lowpass actually have the same response as bandpass www.edaboard.com /ftopic101141.html   (414 words)

Response Time Overview Feedback during the delay is especially important if the response time is likely to be highly variable, since users will then not know what to expect. Normally, response times should be as fast as possible, but it is also possible for the computer to react so fast that the user cannot keep up with the feedback. Therefore, the response time guidelines for web-based applications are the same as for all other applications. www.useit.com /papers/responsetime.html   (1052 words)

Explanatory variable - Wikipedia, the free encyclopedia Its function is to explain the evolution of the response or dependent variable. In statistics, an explanatory variable (also regressor or independent variable) is a variable in a regression model which appears on the right hand side of the equation. When graphing, the explanatory variable is plotted on the X-axis. en.wikipedia.org /wiki/Regressor   (86 words)

PlanetMath: general linear model The response variable is considered random, where as the explanatory variable(s) may or may not be random. Analysis of variance model, or ANOVA, is another special case of the general linear model, where all of the explantory variables are categorical in nature (for example, gender, marital status, etc..). A linear regression model is a special case of the general linear model where all explanatory variables are assumed to be continuous. planetmath.org /encyclopedia/AnalysisOfCovariance.html   (338 words)

The WRX engine A variable intake cam timing engine can use a bit more intake/exhaust valve overlap in the low rpm regions for better off boost throttle response and then close down the overlap and at the same time extend intake closing time, which lets the cylinder fill better for more power. While we might want to say this is because of the variable valve timing, in fact the presence of variable valve timing and the improved drivability is directly attributable to the difference in the fuel the engine is being fed and also the effects of the stringent emissions and fuel economy regulations in the US. The "world motor" we get does not have the Japan variable intake cam timing, which oddly enough can be used to boost low to midrange torque capability as much as it can be used to extend top end power. www.spdusa.com /driving_the_wrx_engine.htm   (338 words)

Tuning Improving Boost Response The intake air control valve opens the variable induction runner when adequate engine rpm is reached, thereby providing sufficient air volume for high speed operation. Enlarging the port area of the intake valves does little for engine breathing unless the intake manifold is enlarged as well By enlarging the intake manifold runners and plenum area, a greater volume of air is available to the intake valves at high engine rpm. The intake air control valves, installed between the cylinder head and intake manifold, are all closed simultaneously by the vacuum actuator when vacuum is applied. www.bajanchameleon.com /200_bhp_glanza_tuning_7.html   (338 words)

Independent Variables and Dependent Variables Consequently the dependent variable is the response that may vary as a function of the independent variable. In an experiment, the independent variable is the variable that is controlled (varied) by the experimenter and the dependent variable is the variable that we measure to determine if the manipulation of the independent variable has an effect. "Independent variables" form the basis of a comparison between groups, conditions, etc, by defining the differences between the groups or conditions around which the comparison is made. core.ecu.edu /psyc/wuenschk/StatHelp/IV-DV.htm   (2624 words)
