R help - Feb 2005 - new package

Dear R-Users,

We would like to announce a new package called "frailtypack". This
package fits a shared gamma frailty model and Cox proportional hazards model
using a Penalized Likelihood on the hazard function. Left truncated, censored
data and strata (max=2) are also allowed.

Future versions will include functions for estimating nested frailty models
using Penalized approach.
