Hi Dear
I have run a multinomial multilevel model using runmlwin, but have got the following error:

OBEY "C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\ST_01000007.tmp"

error while obeying batch file C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\ST_01000007.tmp at line number 76:
calc 'pi'=expo('h')
106331 numeric errors in calculate command, first 20 affected entries listed.
Affected entries replaced with system missing.

What does it mean? Any help is appreciated.

My command was:
xi: runmlwin V_outcome5 V_SEXID cons, level4( CODE_OSTAN:cons) level3( SHAHRESTAN :cons) level2( TheKey2:cons) level1(V_id:) dis

This suggests that MLwiN is having problems fitting the model. I would suggest trying a different base category, or a simpler model to see whether the problem also occurs there.
