You can use the coefficients from a Linear Discriminant Analysis to predict what class a new respondent may be in. To do so, compute the functions for all classes and choose the class with the highest result. This article describes how to go from a Linear Discriminant output
to a table of Discriminant Function Coefficients to use in your predictive model, as shown below:
- A Machine Learning Linear Discriminant Analysis Output. (See: How to Run Machine Learning Linear Discriminant Analysis).
- Select the Linear Discrimination Analysis Output.
- Go to the object inspector > Inputs > DIAGNOSTICS > Table of Discriminant Function Coefficient or click Anything > Advanced Analysis > Machine Learning > Diagnostics > Table of Discriminant Function Coefficient.
