Hi all,
Has anyone tried to do k-fold cross validation for flexible discriminant
analysis ( mda library), for example, using crossval() in bootstrap?
The problem is that the function crossval() requires a separate matrix
for predictors and another for responses, whereas the function fda(),
using the formula argument only.
Is there another way of doing k-fold cross validation for functions
which only have the formula argument, like for fda() and mda() ?
