Apply a PLS Model

Command: Math -> Multiple Regression -> Partial Least Squares Regression -> Apply Model...

The command Math/Multiple Regression/Partial Least Squares Regression/Apply Model... allows to apply a previously calculated and stored PLS model to another dataset. After loading the model the most important model parameters are displayed:

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 [*].

Hint: If one of the independent variables of the model is selected as the target column, the model cannot be applied a second time since the basis of the model will be destroyed. It is therefore recommended to store the results of a model in an empty column (empty columns can be created by adjusting the size of the data matrix).
