Hi there,

I have estimated a random effects negative-binomial model and am not quite
sure about three issues.

1.	What does this part of my output mean? How can I interpret it?

-------------+-------------------------------------------------------------
       /ln_r |   5.141061   .4026877                      4.351808   
5.930314
       /ln_s |   5.041607   .4021128                       4.25348   
5.829733
-------------+----------------------------------------------------------------
           r |    170.897   68.81811                      77.61864   
376.2728
           s |   154.7184   62.21424                       70.3498   
340.2679
---------------------------------------------------------------------------

2.	How can I compute Level 1 and Level 2 residuals given my estimation? Is
there a easy way to test for my iid- and normality-assumptions?

3.	How can I generate a graphs showing different regression lines for my
different groups on Level 2?

Thank you,
Tobi
