Title
[R] matsize -- Set the maximum number of variables in a model
Syntax
set matsize # [, permanently]
where 10 < # < 11000 for Stata/MP and Stata/SE and where 10 < # < 800 for
Stata/IC.
Description
set matsize sets the maximum number of variables that can be included in
any of Stata's estimation commands.
For Stata/MP and Stata/SE, the default value is 400, but it may be
changed upward or downward. The upper limit is 11,000.
For Stata/IC, the initial value is 400, but it may be changed upward or
downward. The upper limit is 800.
The command may not be used with Small Stata; matsize is permanently
frozen at 100.
Changing matsize has no effect on Mata.
Option
permanently specifies that, in addition to making the change right now,
the matsize setting be remembered and become the default setting when
you invoke Stata.
Example
. regress y x1-x400
matsize too small
You have attempted to create a matrix with more than 400 rows or
columns or to fit a model with more than 400 variables plus ancillary
parameters. You need to increase matsize by using the set matsize
command; see help matsize.
r(908);
. set matsize 450
. regress y x1-x400
