Hi Stata expert,
Currently, I am studying Spatial Panel Data. I am currently having trouble with the command I use about Spatial Panel Data. I have read papers and blogs, but my problem is not resolved. Can you advise on my work? I will be happy to provide the data and do-files I have been working on.

command for -xtdescribe- cannot be executed. I tried to get rid of it, it worked finally.

Then -regress $ylist $xlist- cannot be executed. I tried to add xtreg $ylist $xlist, fe- it can be run.

But when it will be tested for model selection it can't. Looks like the command I wrote is wrong. The correct command for -xsmle- is how?

This is where I tested the spatial panel data for the provincial level in Indonesia. Thank you.
