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

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...
