st: Pweight in GLLAMM
Dear All,
I am trying to use GLLAMM to run a bivariate ordered probit model
incorperating the sampling weight. But I failed. The STATA returns "weight
variables wt2 not found".
Here is the code:
gen cons =1
collapse (sum) wt2=cons, by(yy1 yy2 gender education)
gen int pid = _n
gen byte y1=yy1
gen byte y2=yy2
reshape long y, i(pid) j(eqdm)
tab eqdm, gen(d)
gen float x1gd = gender * d1
gen float x1ed =education* d1
gen float x2gd = gender * d2
gen float x2ed = education* d2
eq xx : d2
eq x1 : d1 - d2
gllamm y x1gd x1ed x2gd x2ed , trace i(pid) weight(wt2) family( binomial)
l(oprobit) adapt thresh(xx) eqs(x1)
What is wrong?
Thanks
Li Yu
