local dicriminant basis with wavelets
hi, does anyone already have implemented in R the Best-Basis Algorithm or the Local Discriminant Basis Algorithm using wavelets? for those interested: both algorithms are described in N. Saito, R. R. Coifman: "Local Discriminant Bases" (SPIE vol. 2303, 1994) and can be downloaded here: ftp://pascal.math.yale.edu/pub/wavelets/papers/ldb.ps.gz thanks, till -- ALL THESE WORLDS

Bootstrap error rate of logistic disrmination model
...ut as i can't increase my sample size nor decrease the number of covariates, I am hoping this could work. Maybe adjusting the bootstrap function to maintain the same group ratios as the original data when the bootstrap sample is randomly chosen. I have been using the bellow function for linear dicriminant function error bias estimation but when using it for my logistic models i come into problems with the predict function calculating probabilities instead of group allocation as for lda(). In that case maybe someone knows of a function which predicts goup allocations for data in a logistic reggressio...
