Re: st: Re: The speed of the MFX command and Stata 9
my initial experience with -mfx- taking more than 39 hours after a -herprob-
estimation was based on a model with 44 regressors and 87 000 observations,
CPU speed 1,92 Ghz, and the following version of Stata 8:
. update query
name of file: wstata.exe
currently installed: 23 Jan 2003
latest available: 10 Jan 2005
Indeed, it does not look very updated. I am about to update it and I'll run
the model again afterwards to see if there is a difference.

I would like to hear more about your experience with -mfx-. When you
say that the large model had not finished after 39 hours, are you
talking about Stata 8.0 or Stata 8.2 with all the latest updates? I
recall that the speed of -mfx- was increased significantly after the
initial release of Stata 8.

I have made the experience that -mfx- has been considerably speeded

My experience relies on -mfx- after the heteroscedastic probit
model -hetprob-. For example, in one model Stata 8 took 3:24 hours
compute- after -hetprob-, while Stata 9 took 1 minute 24 seconds. A
model hadn't finished after 39 hours in Stata 8, but it took only
10 minutes in Stata 9.
