st: re: statsby slowness
"E. Paul Wileyto" <[email protected]> replied:
For large numbers of "by groups," I have found it works better/
faster to write my own script that repeatedly pulls the original
file from a tempfile, and then uses a keep statment to restrict the
analysis. Statsby spends too much time looking to see who is in.
I'll do that. Cheers. Gene microarray data have stupidly large
numbers of by groups these days. Offlist, Michael Blasnik rote that
the official statsby incorporated his speed improvements already, so
the speed is what it is for the spearman command. Other commands are
much faster (like regress). Since my posts, I've found the ranking
the data and running corr speeds considerably. Also running statsby
on subsets of the data and appending results is faster.
