[R] zero inflated poisson and censored-continuous models

[Georgina.Bermann@astrazeneca.com]

I wonder if there is a package that will estimate a Zero Inflated Poisson
Model (ZIP), and also if there is a package that will estimate what is
called the Tobit model: that is a combination of censored and observed
values in the same sample.
