[Limdep Nlogit List] Partial Effects for Tobit Fixed Effects Model

[Shirsho Biswas]

Hi,

I have estimated a Tobit Fixed Effects model. The model includes a couple
of binary dummy variables. Hence, instead of computing partial effects at
the means of all Xs (which doesn't make much sense for binary variables), I
wish to compute partial effects averaged over all data observations.

By specifying the model as:

TOBIT ; ...; FEM; Cluster; Partials$
PARTIALS; Effects: ...., Summary$

I do get the partial effects from the Tobit command as expected (computed
at the means of all Xs)

The second PARTIALS command gives me the following error:

"Previous model did not store model setup for PARTIALS.
Check model setup and output for errors. Setup does
not occur if model command contains Expand(variable)"

Is this problem caused because of the Fixed Effects? Is there any way, that
I can compute the partials that I need?

Best,
Shirsho
