Re: st: stata runs slowly

[Sabina Kummer <sabina.noo@postmail.ch>]

Hi,

Did you try to set the number of maxvar before running the command?

I suggest you to determine the number of maximal variables (set maxvar) and the memory (set memory). You can also increase the matsize (set matsize). 

You can find further details on these 3 commands in the "HELP" in Stata.

Best regards,

Sabina

Hi,

I have a problem with Stata running very slowly.

My population contains about 1 mio observations. I am doing an
cox-regression analysis, stratyfied on families:

stcox i.education, strata(family-id) vce(cluster person-id)

This command runs without any problems.

However, when I want to perform the following un-stratyfied analysis -
where I am still taking into account that some of the persons are
related - , it takes stata several hours to do so:

stcox i.education, vce(cluster family-id)

Can I do something to make this run faster?

Thank you
