  LOGIT
LOGIT is used to estimate a conditional and/or multinomial logit model.
There are three types of logit model: those where the regressors are the same across all choices for each observations, i.e., they are characteristics of the chooser, those where the regressors are characteristics of the specific choice, and mixed models, which have regressors of both kinds.
In the second case (conditional logit), the regressors change across the choices, and a single coefficient is estimated for each set of regressors.

  PA 765: Logit, Probit, and Log-linear Models
Logit and probit extend the log-linear model to allow a mixture of categorical and continuous independent variables to predict one or more categorical dependent variables.
Where the logit transformation is the natural log of the odds ratio, the function used in probit is the inverse of the standard normal cumulative distribution function.
Probit coefficients correspond to the b coefficients in regression or the logit coefficients in logit or logistic regression.

 Multivariate Analysis UCR Sociology 203A Logit and Probit Example
The logit and probit regression models regress a function of the probability that a case falls in a certain category of Y, on a linear combination of X variables.
The logit model is exactly that: the left hand side is the logit of Y, or the log of the odds that a case falls in one category on Y versus another.
Logit and probit models use the method of maximum likelihood to fit functions of proportions of cases at each level of the X vector that have a score of "1" on the dependent variable.

 Logit Analysis for CBC
Logit analysis is an iterative procedure to find the maximum likelihood solution for fitting a multinomial logit model to the data.
After logit converges on a solution, the output is displayed in the results window, and you are given the option to save the run to the utility file.
To see how logit output and analysis by counting choices output are similar, we use the same procedure to estimate the distribution of choices for four concepts differing only in brand, plus a "None" option.
