How to: Discriminant analysis classifier in JMP11?

Hallo everyone and thanks for all your help in advance. I am relatively new to JMP so I have still some blank spots in a few JMP applications. I have performed a discriminant analysis (quadratic) in a series of data, got quite good results and categorized my data in 4 different classes. Now, I have done the exact same study in a new set and I have a completely new series of data (of the same variables) which I would like to classify in the classes I have produced in my previous analysis. Is this possible and if yes, how can it be done in JMP?

Thanks, Tasos

Check out the 'Save Formulas' option under the red triangle in the report.

To see this, run this JSL (do 'File > New > New Script', cut and paste, then 'Edit > Run Script'):


dt = Open("$SAMPLE_DATA/");

disc = dt << Discriminant(X( :Species ), Y( :Sepal length, :Sepal width, :Petal length, :Petal width ));


disc << SaveFormulas;

Look at the formula in the 'Pred Species' column that is saved to the table (click on the '+' sign next to this column in the Columns Panel). If you add new rows to the table, these will be scored using this formula.
