Topic: Blocking (statistics)

	Blocking (statistics) - Wikipedia, the free encyclopedia
		In the statistical theory of the design of experiments, blocking is the arranging of experimental units in groups (blocks) which are similar to one another.
		The sex of the patient is a blocking factor accounting for drug variablility between males and females.
		This design will be more sensitive than the first, because each person is acting as their own control and thus the control group is more closely matched to the treatment group.

	Statistics Glossary - design of experiments & ANOVA
		The randomised complete block design is a design in which the subjects are matched according to a variable which the experimenter wishes to control.
		Using a randomised blocks design, the subjects are assessed and put in blocks of four according to how severe their skin condition is; the four most severe cases are the first block, the next four most severe cases are the second block, and so on to the twentieth block.
		The four members of each block are then randomly assigned, one to each of the four treatment groups.

		Meanwhile, a blocking probability of 1% is reached at 81% load and a blocking probability of 0.1% is reached at 60% load, for the case where there is a 33% wavelength conversion requirement.
		Meanwhile, a blocking probability of 1% is never reached (regardless of switch load) and a blocking probability of 0.1% is reached at 97% load, for the case where there are 2.2 times as many external input ports as internal input ports.

	The Harvard Crimson :: News :: Size Does Matter
		Last week's long-anticipated blocking statistics offer the College a positive-but tentative-sense that some of the adverse effects of randomization predicted by its critics may not be born out in practice.
		But their other major concerns is that large blocking groups insulate students from the ideals of randomization by reducing their motivation to get involved in House community beyond the confines of the blocking group.
		Blocking should be addressed far before first-year housing forms are due in March so as to explain that a blocking group should never encompass one's entire social circle but rather provide students with a core of companions with which to experience and identify with their specific house.

	Ecology: Blocking factors and hypothesis tests in ecology: is your statistics text wrong?
		Blocking factors differ from treatments in that they have not, or cannot, be applied randomly to the experimental units.
		Statistically, blocks are thought of as a source of nuisance variation; biologically, this need not be the case.
		We can use the F ratio as a test statistic for testing the null hypothesis that the variances from two populations are equal.

	Empirical Analysis of Internet Filtering in China
		This reduction in blocking of entire news sites may reflect that certain new filtering technologies (discussed in greater detail in the appendix) allow blocking only of the particular sections and articles that are particularly controversial in China.
		Also blocked was the entirety of uscourts.gov, including the many federal district and appellate courts in the United States, as well as the United Kingdom's Court Service and Israel's Judicial Authority.
		The primary and most longstanding means of blocking is at the router level, and on the basis of IP address -- the crudity of which means that those implementing filtering must choose between blocking an entire site on the basis of a small portion of its content, or tolerating such content.

	Univariate Statistics - Randomized Blocks
		If the Treatment x Blocks interaction is significant, then we will know that the effects of the treatments do not generalize across the abilities or classifications of subjects represented in the experiment.
		It should be noted that the degree to which blocking results in a reduction of the error term depends on the magnitude of the correlation between the scores forming the basis of the blocking and the scores on the DV.
		If the blocking factor is not highly correlated with the DV, we may actually lose power since we will have just as heterogeneous a population as in the SRD and we are needlessly giving up degrees of freedom to account for the blocking factor.

	Blocking
		Blocking neutralizes background variables that can not be eliminated by randomizing.
		A block is ususally used when this uncontrolable factor cannot be avoided during the experiment, so it is incorporated into the experiment in a controlled way.
		The idea is to pull the variation due to the blocks out of the expermental error in order to reduce the experimental error and give the test more power.

	Network dynamics
		Here we present an example of bursty statistics from a different class of complex system in the area of irregular traffic flows on regular networks.
		Further investigation of the phenomena reported there show that traffic flows on the model network, whose structure is static and which supports constant traffic demand, can display bursty and intermittent behaviour; an example of the time series produced is shown below (Figure 9).
		For completeness, we now show the time series (Figure 13), the blocked packet distribution (Figure 14) and the subsequent unblocked packet distribution (Figure 15) for a 30 by 30 grid with 39 percent of the sites occupied by packets.

	Blocking and Nonblocking Multirate Clos Switching Networks (Site not responding. Last check: 2007-11-07)
		The blocking behavior of blocking switches supporting multicast connections is investigated by means of simulation.
		In this way, the internal blocking statistics that truly reflect the switch performance can be gathered and studied.
		In addition, when small blocking probability can be tolerated, our results indicate that situations with many large-fanout connection requests do not necessarily require a switch architecture of higher complexity compared to that with only point-to-point requests.

	Extending the PassThru NDIS IM Driver - Part 2
		It is important to insure that the overall design of the IP Blocking design does not prevent the PassThru driver from being unloaded on demand.
		Spin locks are used in some cases; in other cases, it suffices for purposes of copying statistics counters merely to employ code that preserve cache coherency ("interlocked" family of functions).
		For purposes of statistics, the author does not believe such serialization would be worth the trouble.

	Blocking RSS advertising (kottke.org)
		Given that people who use newsreaders are still of the early adopter sort who are used to blocking ads with Firefox or fast-forwarding through commercials with their TiVos, it seems likely that blocking advertising in RSS/Atom files might soon become an issue.
		Ad blocking then becomes a problem itself, because I generally use RSS feeds to browse information I find interesting, and would prefer not to impose limits on viewed content if I am going to have to filter out disguised ads.
		My suggestion to the content providers who have a large portion of their audience blocking advertising (whether it be on the web, or in a feed) is to offer a low-cost premium model with no advertising as one of the benefits (if not the only benefit).

	VSS examples - 3: Network dynamics - computer simulations
		A square grid of N by N cells is scanned from the NW corner to the SE corner in a raster (or other sequence) by a token, which alights on each cell in turn and enables development to occur.
		Preliminary investigation of the phenomena reported there shows that traffic flows on the model network, whose structure is static and which supports constant traffic demand, displays bursty and intermittent behaviour for certain values of f; a further example of the statistically self-similar time series produced is shown in Figure 14.
		An even more striking example of clumping and free flow is provided in the time series (Figure 18), together with the blocked packet distribution (Figure 19) and the subsequent unblocked packet distribution (Figure 20), for a 30 by 30 grid with 39 percent of the sites occupied by packets.

		If users block cookies, accurate short-term measurement is compromised, relegating increasing numbers of Web visitors to "anonymous" status.
		The report found that as many as 39% of online users may be deleting cookies from their primary computer monthly, undermining the usefulness of cookie-based measurement and leaving many site operators flying blind.
		The JupiterResearch report provides advice to site operators for how to cope with the decline in accuracy of visitor measurement and predicts that Web analytics vendors will adapt their tools in the face of a consumer landscape that makes established measurement practices unreliable.
