- Binary logistic
- This term is used in SPSS for
regression analysis using the log odds of a
- Others refer to the method as
dichotomous logistic regression.
- Multinomial logistic
- SPSS uses this term for regression
analysis using a polychotomous variable.
- Other refer to it as
polychotomous logistic regression.
- SPSS says
- Multinomial Logistic Regression
is useful for situations in which you want to be
able to classify subjects based on values of a set
of predictor variables. This type of regression is
similar to logistic regression, but it is more
general because the dependent variable is not
restricted to two categories.
- Discriminant Analysis
- This term usually embraces both
the case of dichotomous and polychotomous dependent
- That is the practice in SPSS,
which offers discriminant analysis as an option
- Discriminant analysis approaches
the classification of cases in two or more groups as a
problem in multiple analysis of variance of
differences between and within group
