I am using xtmixed to analyse a dataset which is both unbalanced and has missing
values:
xtmixed sc c.et##jaw##bracket##sex##fmpa || pid:,
and subsequently anovalator, from ATS, to investigate the interactions, but it
fails as follows:
. anovalator bracket jaw sex,main 3way
anovalator main-effect for bracket
chi2(1) = 2.3637885 p-value = .12418029
no such variables
r(111);
. anovalator jaw, main
no such variables
r(111);
The error seems to be related to jaw which has 2 levels(1,2), bracket has 3 and
sex 2.
If I run
margins jaw##bracket##sex##fmpa, post asbalanced emptycells(reweight)
I can test jaw.
. testparm i.jaw
( 1) 1bn.jaw = 0
( 2) 2.jaw = 0
chi2( 2) = 9290.22
Prob > chi2 = 0.0000
. test 1.jaw = 2.jaw
( 1) 1bn.jaw - 2.jaw = 0
chi2( 1) = 29.75
Prob > chi2 = 0.0000
I would be grateful if somebody could tell me what I am doing wrong with
anovalator.
Thank you,
Arti
