Dear all, I am running a multilevel regression model by -GLLAMM-.The initial
results are good but then the program reports "overflow at level 1 (173 missing
values)".It keeps reporting this msg for a long time.Anyone has a hint about
this?Seems very few resources are available on the web for this issue, except
"http://www.ats.ucla.edu/stat/stata/examples/mlm_ma_hox/chapter4.htm".Searching
by "overflow" you can find this issue happens to the demonstration that
"overflow at level 1 ( 2000 missing values)".

For you information,my command are
-gllamm location eatr cdrug2 dist ap sisters2 wage3 edu3 cai share if
highgrow==1&deudmy==0, nocons expand(id choice o) i(parentid2) lin(mlogit)
family(binom) nrf(10) eqs(eatr cdrug2 dist ap sisters2 wage3 edu3 cai share
cons) nip(8) trace adapt-

level 1 is for subsidiaries, level 2 is for their multinational parent.It is a
location choice problem with all independent variables the location specific
variables together with a constant.

Thanks in advance.

Kevin
