Hi Statalists,

I keeps getting an error message, ""pweights must be positive", when using the "mixed" command.

Array

I have checked that the values of weights for both levels are all positive. I'm using Stata 14 version. I'm not sure why it keeps showing this error message.

The same question has been asked in the forum in the post from 2018, 2016, and 2014

However, my question is: is there any way I can apply the pweights without changing the "mixed" command to "svy"?

Thank you for your help.
