| Subject | st: is merge old version faster? |
| Date | Wed, 03 Oct 2012 17:38:28 +0200 |
Dear Stata Users,I am checking a new command computing the net survival according to Pohar Perme method, -stnet-.
Internally the command must repeatedly merge two files.When -merge- is specified according to the version 10 syntax it seems that -stnet- is faster than in the case -merge- is used according to the version 11 or 12.
Has anyone else noticed that -merge- old version is faster than -merge- new version?
If yes, what could be the reason? Do you know a way to make faster the merging of files?
