Hi all.
I have a question about discriminant analysis operators .....i want to know where its results come from? for example when i run PC analysis i get an eigen value and eigen vector from results so i know where these pc come from...but how about discriminant analysis ?? how those probabilities are calculated? i know there should be some formulas..... something like eigen vector and value ...but how can i get it?
Thanks

Hi,
actually there is no easy way to get the internals of the LDA via the GUI. Of course, the model knows all relevant measures and calculations, but they are currently simply not displayed in the GUI.
It may be possible to access them via the scripting operator, but that requires to read some java code (the code of the LDA model in RapidMiner) and to produce Groovy Code (to extract the necessary values from the model object with the Execute Script operator).
Best regards,
