st: RE: mat size
Ines:
Apparently you are trying to estimate a fixed effects regression by adding
dummies. A better way of doing the fixed effects regression is -xtreg- with
the fe option. see: -help xtreg- and the entry for -xtreg- in the xt manual.

Subject: st: mat size
Dear list-members,
I am trying to run a OLS regression with panel data (8240 observations)
The explaining variable have 1203 categories
I estimate the following model:
set mem 50m
set matsize 800
xi: reg perform i.codempr
but the outcome is:
i.codempr _Icodempr_1-1203 (naturally coded; _Icodempr_1 omitted)
matsize too small
You have attempted to create a matrix with more than 800 rows or columns
or to fit a model with more than 800
variables plus ancillary parameters. You need to increase matsize using
the set matsize command; see help matsize.
