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.
r(908);

An answer would be very helpful.
 
Thank you,

Ines
