Good morning,
I'm a basic Stata user (version 15) and I want to do some analysis with PISA(2015) data.
In order to take into account the complex survey design in the estimation of sampling variances, I have already installed the command -REPEST- from SSC. Now I want to run several multilevel models with the command xtmixed but I have some problems in obtaining information that I want.
The command that I used is the following:
repest PISA2015, est (stata: version 15: xtmixed PV@MATH || cntschid:, nolog mle var ) fast store(m1)
and this is the output that I've obtained...
What I cannot understand is how can I get the "standard" xtmixed output, with Log Likelihood, var(_cons), var(Residual), number of obs and groups and so on. I would like to calculate "bic" and "aic" but I don't know how to do it and I cannot find useful instructions in the Repest help file.
I hope I explained myself correctly,
thank you!
