Save Commands
If you have ordinal or nominal response models, the Save Probability Formula command creates new data
table columns.
If the response is numeric and has the ordinal modeling type, the Save Quantiles and Save Expected
Values commands are also available.
The Save commands create the following new columns:
Save Probability Formula creates columns in the current data table that save formulas for linear
combinations of the response levels, prediction formulas for the response levels, and a prediction
formula giving the most likely response.
For a nominal response model with r levels, JMP creates
• columns called Lin[j] that contain a linear combination of the regressors for response levels
j =1,2,...r -1
• a column called Prob[r], with a formula for the fit to the last level, r
