Re: st: SSC activity, October 2004

Roger,

I was going to refer you to my earlier postings to Statalist on this 
matter, but I find that postings earlier than 2001 are inaccessible 
from either Harvard or Yahoo links. The issue, as I alluded below, 
refers to how one credits an archive access to multiple authors (my 
method there is just to credit each author with the access) and how one 
deals with multiple-ado packages. What is counted by the web server log 
is the access of one ado-file. Many packages have multiple ado-files. 
It would seem that every successful installation of a package should 
include N hits for N ado-files, as you suggest; but some people don't 
use 'ssc' to do this--they use a web browser, and in doing so are free 
to view one .ado without viewing another. Also, if only some of the 
ado-files in a package have changed, Stata will only download those 
that are needed. For these reasons, the 'npkghit' indeed can be 
non-integer. The relevant code from the processing routine is:

sort author package
gen npkghit=nhit/nmods
collapse (sum) npkghit,by( author package)
gsort -npkghit

where 'nhits' is the number of ado-file downloads, 'nmods' is the 
number of ados per package.

Thanks
Kit
