st: Can I compare [xtnbreg, re] with [xtnbreg, fe] using LR test in Stata?

[Muhammad Anees <aneesmkhattak@gmail.com>]

Hi statalister!

I have one simple question and found no clue to clear my confusion.
When I run stata's [xtnbreg, re] command, the results for LR test at
the end of output compares the model selected with pooled model.

My first question is that, how can I interpete these results? when I
have not given any option to [xtnbreg, re] to show this result.

Furthermore how can I compare the [xtnbreg, re] with [xtnbreg, fe]
using the same LR test as previously. Is there any option with
[xtnbreg, re] in stata which compares the results of [xtnbreg, re]
using the LR output at the end with [xtnbreg, fe] instead of its
default ( I assume) pooled.

What stata command gives these results instead.

Thank you very much for your suggestion.
