Hey GRETL-USER
May you can help me with a problem.
I tried to generate AME with the
script from
http://www.learneconometrics.com/gretl/using_gretl_for_POE4.pdf
p. 379-380, but it wont work.
The Error:
? ame(&coef, x)
Liste hat 12 Elemente, aber Länge des Vektors b ist 13
*** error in function ame, line 1
What means the list is short by one.
List x is all regressors (11) of a ordered probit plus the constant. So it got 12
elements. May it is the DV missig for the Calc? But where to put it?
Thanks
J.I.

The dependent variable is not part pf the calculation. However, I'm
not sure if Lee Adkins' ame() function is set up to handle ordered
probit. In an ordered model you have one or more "extra" coefficients
("cut points") which do not correspond to members of the list of
regressors, and I guess that could account for the mismatch here.
I suspect that one of Oleh Komashko's function packages can handle
average marginal effects for ordered probit. Oleh?

Dear Allin, a_aeff as of current version still can compute only point effects A year ago I
wrote some functions (I gave them only for my students) but they can't deal with
functions I do not remember how many models I coded I have to some work for my department
I'll try to sent something in one or two days

Take it easy, Oleh. It was only a question whether that stuff is
_already_ covered by one of your packages, not that you have to work
hard :-)

Dear Sven, I'm lazy, but ambitious, and often I have the strength of will enough to
overcome. I will Oleh
