question about train_SWLDAmatlab.m #215

Closed manipulative closed 5 years ago

manipulative commented 5 years ago

Hello. I am looking for matlab code about stepwise Linear Discriminant Analysis. And I find bbci_public. It's really a great tool. But I find it that train_SWLDAmatlab.m use stepwisefit function which of Statistics and Machine Learning Toolbox. Is stepwisefit function only fit to linear model? Or there are some references support that stepwise function is also fit to LDA? Looking for your reply.

I do not really understand your question, since LDA is a linear model. The function train_SWLDAmatlab.m can be used for applications of stepwise LDA as in the BCI literature.

Best regards, Benjamin Blankertz

Thanks for your reply, I think you are right. I thought that stepwisefit could only be used in general linear model. But I found some reference yesterday say that two classes LDA is very similar to GLM, so it's appropriate to use stepwisefit in LDA. Thanks for your reply again.
