[Limdep Nlogit List] new variable LOGL_OBS created LIMDEP itself

[weng06 at vt.edu]

I wana do the regression.

Before I did the regression, I rejected the observationss with missing values in
the independent variables. But after I ran the regression, LIMDEP created a new
variable LOGL_OBS by itself.

How to deal with this problem?
Anyone once come across this problem?

Thanks.
