It depends on how your data is arranged and whether you have balanced or
unbalanced panels

See R6.5 & E17.4

For balanced panels you need to specify the group size

;pds= panel specification



Using your variable names from below



;lhs=Z I=N, T=X

;rhs=one,independent variables



;random effects





For unbalanced panels you need to create a variable that indicates group




The following is an example of the script I might use for creating a
group count variable for unbalanced panels


sample; all$


sort; lhs=Xsessionindex; rhs=*$

create; Xsession=ndx(Xsessionindex,0)$

regress; lhs=one; rhs=one; str=Xsession; panel$

create; Sessionsize=_groupti$



;lhs= lhs=Zti

;rhs=one,independent variables



;random effects

Subject: [Limdep Nlogit List] random effects probit with clustering


I have panel data comprised on X sessions with N subjects per session
each making Z yes/no decisions.  I want to estimate a random effects,
probit model with clustering on session.  Is this doable with Limdep and
if so how?


Thanks for any help provided.
