Hi --
Does anyone have experience fitting Nested Logit Models as defined in the
text by Ben-Akiva and Lerman (1985) in S-Plus? These models are used
extensively in civil engineering applications like transportation and
modeling how available modes of transportation will be utilized. I
presently use SAS to fit "generic", non-nested multinomial logits. That
package will soon have the capability to fit nested logits, but it will be
part of a module that we don't purchase and I will probably be unable to
justify my company purchasing it.
Estimating these models is not a trivial task, and I'd like to avoid
programming the estimation myself if someone has had experience with it.
If no one has done this in S-Plus, does anyone have information on other
packages that may work (I understand Limpdep and Stata are two
possibilities . . . any idea about available C++ or Fortran code to do
this?). Thanks.
