Regression - Save Variable(s) - Probabilities of Each Response

Creates a new variable containing predicted probabilities of each response from a model (e.g., from Regression - Ordered Logitordered logit).

Output

Running this QScript will produce a new variablevariable, which will appear in your data setdata set for use in further analyses.

Technical details

Uses the probabilities method from R. Unlike the defaults in most R packages, this implementation assigns predicted values for observations not in the estimation sample.
