Apply an LDA Model
The command Math/Linear Dicriminant Analysis/Apply Model... allows to apply a previously calculated and stored LDA model to other datasets. After loading the model the most important model parameters are shown:
When clicking the button "Apply Model", first the validity of the model is checked by matching the model variables and the variables of the current dataset (the matching is performed by comparing the variable names). If the variables match, the user has to select the target variable, otherwise an error message is displayed. The target column is named after the model name and is marked by the preceding string [*].
As an option you can create the raw classifier estimates by unchecking the box "Create Dichotomous Results". If this box is checked (which is the default case) the classifier uses the original target values to indicate the result.
