I'm using xtabond2 to run some regressions. My panel dataset contains 1674
observations with data for each state by year and quarter. Not all states
have observations for each quarter.
When I attempt to run the regression:
xtabond2 Investment l.Investment pi, gmm(l.Investment)
I get an error stating:
".no room to add more variables due to width
An attempt was made to add a variable that would have increased the
memory required to
store an observation beyond what is currently possible. You have the
following
alternatives:
1. Store existing variables more efficiently; see help compress.
2. Drop some variables or observations; see help drop. (Think of
Stata's data area as
the area of a rectangle; Stata can trade off width and length.)
3. Increase the amount of memory allocated to the data area using the
set memory
command; see help memory.
r(902);"
I've increased the matsize (to 800) and memory and I continue to get an
error saying there is not enough space to run the regression. Does anyone
know if xtabond2 has a limit on the size of the dataset? If so, what is it
and is there a work around?
Thanks,
Kevin Christensen
P.S. I'm running SE 9 on Win XP pro.
