(I just bought a copy of Prof. Gu's new book at the JSM, so I'll be learning more about `gss'.) I believe Loader's `locfit' package also does smooth logistic regression via local polynomial (as `sm'), but with several automatic bandwidth selection procedures. gam() in the recommended package `mgcv' can also be used, I believe.

I am concerned about my choice of bandwidth, and I was hoping there was another method available in some other package, perhaps with an automatic choice of smoothing parameter. Does anyone know of one? Thanks in advance.
