SE calculation missing

[Nahid Mia]

Dear Expert,
I would like to calculate the mean and standard error using a complex survey design. However, I found an error after running the command. Please see below:

svyset HH1 [iw=HW], strata(strat)



It will be highly appreciated if you kindly provide some explanation on it.

Thanks in advance
Nahid

Nahid:
the footnote reported below the outcome table seems to explain what you experienced.
As an aside, please note that the FAQ remind us not to post screenshots but to use CODE delimiters instead. Thanks.
