[R] statistical prediction for glm()

      The help page for "predict" says it is a generic function.  Then 
command 'methods("predict")' reveals a function called "predict.glm", 
which has its own help page.  Does that provide what you want? 

      Also, I didn't find your earlier post in "www.r-project.org" -> 
"search" -> "R site search".  I found 15 hits for "martin wegmann 
prediction glm", but none that looked like your question below;  perhaps 
someone else can explain why I didn't find your earlier post.  I also 
found 25 hits for "statistical prediction for glm".  Have you looked at 
those?  One or more of them might help you.

hope this helps.  spencer graves
