Is NLOGIT 6 good for all types of logistic models, like Multinomial Logit model, Mixed Logit mode, Conditional Logit model, nested Logit model, and others?
NLOGIT is great for discrete choice modelling. You can estimate all of the models you have enumerated. The advantage in my opinion is that it is relatively easy to estimate a model, at it is quite flexible (for example allowing choice sets to vary across choice occasions). There are a few very well-written books that use NLOGIT examples.
However, it presents some disadvantages. First, it is an expensive software. Second, for example, if you specify a mixed logit model, the maximum number of parameters that can be random is 25. Moreover, there is a limit to how many observations you can have per dataset (it was quite a high limit, but my dataset was longer than allowed). Also, since there are fewer users, the online help forums are less active.
Nlogit contain a large array of tools for data analysis, data management and containsmodel building from simple linear regression to maximum likelihood estimation of nonlinear systems of equations, with many extensions and the variations. Nearly all techniques used in modern empirical investigation containsare provided.
It is a very good sofware in discrete choice modelling but it is expensive (about 1000 $).
Python Biogeme is another valuable alternative.modeling software.
