Objects incorporate both data and the ability to manipulate it.
This approach allows us to write programs that are just as simple as those of a conventional econometric package. Output tables showing the parameter estimates and statistics will be sent to the file probit.out as well as to the screen. Analytic Hessian matrices are used in the maximization algorithm. We include a collection of classes that represent particular econometric models. Each can be used in a short program to estimate the model parameters, just like the Probit class.
