Error: running sem re using xsmle

[Souryabrata Mohapatra]

Hi everyone,

I used spmat and xsmle to do spatial panel analysis and successfully run-

xsmle $ylist $xlist, wmat(w) model(sdm) fe
xsmle $ylist $xlist, wmat(w) model(sdm) re
​​​​​​​xsmle $ylist $xlist, wmat(w) model(sar) fe
​​​​​​​xsmle $ylist $xlist, wmat(w) model(sar) re
​​​​​​​xsmle $ylist $xlist, emat(w) model(sem) fe
xsmle $ylist $xlist, wmat(w) emat(w) model(sac) fe

But as I run the following command I get an error message that initial values not feasible r(1400);

​​​​​​​xsmle $ylist $xlist, emat(w) model(sem) re

Can you please advise how can I overcome the error?

Thanks,
Sourya
