Dear Statalisters,
I'm executing a series of 6 tests (5 lincoms & 1 F-test) after a regress
statement. Then I ask outreg to report these results using the addstat
option. This is repeated 4 times (for 4 different specifications) so that my
resulting outreg output has 4 columns of results. Everything goes fine for
the first specification. In the other 3 specs, though, the SEs on the
lincoms are reported out of order. (Omitting coeff's) I get:
Col1 Col2 Col3 Col4
se1 se4 se2 se3
se2 se1 se1 se5
se3 se3 se3 se1
se4 se5 se5 se2
se5 se2 se4 se4
Previously, I had a problem where an entire lincom statement would repeat in
my outreg and Patrick Joly solved it. (It was due to the fact that outreg
was written for Stata 6 and only understands variable names of 7 characters
or less.) Perhaps this is related.
I'd really appreciate any help. This seems v. strange. Note that if I trim
the text in the addstat option (i.e. Lincom test 1, est1, SE, se1) - see
below - the problem remains but the order changes.
This is my outreg statement:
outreg2 _IpreCap_1 postCap
using famCap4_parity1_race`i',
title(Relative Changes in the Abortion Ratio Among Race=`i')
ctitle(Base)
addstat(Lincom test: postCap + parity>=1 + (parity>=1*postCap),
est1, SE, se1,
Lincom test: preCap + parity>=1 + (parity>=1*preCap),
est2, SE, se2,
Lincom test: (parity>=1*postCap) - (parity>=1*preCap),
est3, SE, se3,
Lincom test: (parity>=1*postCap) - (parity>=1*preCap) -
parity>=1, est4, SE, se4,
Lincom test: preCap + (parity>=1*preCap), est5, SE, se5,
F-test: preCap + (parity>=1*preCap) = 0 & preCap = 0,
fstat1, Prob, prob1)
addnote("", "Base regression: ln of abortion ratio on age, parity,
pre-cap,",
"post-cap, unemployment rate, max AFDC benefit, year",
"Alt1: base regression w/o time dummies",
"Alt2: base regression w/ interaction of parity & year",
