Hi Sharad,
gllamm is known for its slowness. I seem to remember that there was once a
website which says that you can upload your data and they'll run your
analyses for you in a supercomputer. I can't find it since. Maybe it is no
longer available.
Another issue is: you probably reduced your number of integration points
to 5 to save time, but are you sure it's sufficient for your purpose?
Hope that helps.
Tim

st: running gllamm in stata
Hello,
Based on the GLLAMM manual I tried to run two level
random coefficient model for binary outcome variable.
It took about 4 hour to run the model. I suspect I
could not input the comands correctly. I am also not
clear about defining matrix, equation and other
options. May I request for your help? Data source,
variables and syntax which I used are as follows,
Data source is women nested within village (average
women per village is 10, minimum4 maximum 80). There
are 2 level2 variables and 6 level1 variables, with
n=1060
Level 2 (village) variables: vi24 vi26
Level 1 (women) variables: svcompr (dependent with 1
yes and 0 no), bpod, anctrain, ddiff, crillnes,
delhist, alcohol
Input comands were as follows,
. gen cons=1
. eq inter: cons
. eq slope: anctrain alcohol crillnes delhist
. matrix a = e(b)
. matrix a = (a, .2, 0)
. gllamm svcompr anctrain alcohol crillnes delhist
vi24 vi26, i(vill) link(logit) family(binom) nrf(2)
eqs(inter slope) nip(5) copy adapt eform
My questions are, whether the comand is correst? if
so, how can the computer be made to run comand faster?
If it is not correct, what would be the correct
comand.
Hoping appropriate suggestions,
Sincerely
Sharad
