Response information

Minitab displays this information about the response:
Name of the response variable
Levels of the response variable
Number of observations at each level of the response variable
Number of nonmissing observations

The output also identifies which level of the response is the reference event.


Use the response information to examine how much data are in the analysis. Larger random samples with many occurrences of each level usually provide more accurate inferences about the population.

Also use the response information to determine which event is the reference event. Interpretation of statistics like coefficients and odds ratios depend on which event is the reference event. You can change the reference event for the response in the Nominal logistic regression dialog box.
