the second question is more for the Stata staff. i noticed that the
svy: tab command in version 9.0 takes significantly much longer time
to present results. why does Stata 9.0 regress in term of speed in
this particular routine? how can i speed up estimation process in
svy: tab.
Jeff Pitblado offered this discussion of speed issues back on Aug. 9:
There are two reasons for the difference in speed between -svyregress- and
-svy: regress-.
1. Compiled code written in C is faster than Mata, although compiled Mata
code is very fast compared to interpreted Stata code.
2. General purpose code tends to be slower than code written to take
advantage of a special case.
If possible with your data, you can use the older & faster svy
commands by using version control.
