[Limdep Nlogit List] Help with "Error 699" internal limit

[Emmanouil Mentzakis]

Hello,

I'm trying to estimate a linear panel model with a random effect on
the individual level. -pid- is the person identifier and it takes
values from 1 to 13428.

e.g. Regress; Lhs = Y; Rhs = ONE, X; RPM; REM = pid ; Pds = count$

However, Error 699 is returned: "Error 699: PID is not an integer
1-9999. Obs. 48762= 10000.0000".

Is there any way I can increase such internal limit or circumvent this problem.

Thank you in advance

Regards,
Manos
