Dear Murod Aliyev,
this is really a problem with -svyselmlog-. You can write to Rafael De
Royos, the author of -svyselmlog- but I dont know if he will have a
solution.
You can use the -force- option.
To solve this problem, I used -svydes, finalstage- and dropped the
single #obs, but I dont know if this procedure is correct...but after
this, the -svyselmlog- runs.
HTH,
Joao Lima
