Hi all
I have a statsby regression that I'm performing over a list of 100 cases ("Units"). I'd like to collect the regression coefficients from the various terms to analyze, so I'm using the following command:
.statsby "anova logcpint benchdwellmin hyb benchdwellmin*nMES nMES /nMES|die / nMES|die|atom / ,continuous(benchdwellmin) partial regress anova" _b, by(unit) saving(betas.dta)
The problem is, when I run this I get an error:
regressor c1 not found
error in statistic: _b[c1]
r(111);
This appears to happen immediately following the first Unit analysis. The problem is, when I have a look at the coefficient matrix directly, there appears to be no problem:
. matrix list e(b)
c1 c2 c3 c4 c5 c6 c7 ...
r1 7.8317621 -.00012466 .16011793 0 -.01768075 0 -.00007796
_b[c1] is clearly defined, but statsby seems to have trouble snagging it. Am I interpreting the situation correctly? Is there a problem with the statsby statement?
Help!
