NEW release of FRAILTYPACK
...w available from
CRAN. The package fit general frailty models using penalized likelihood
estimation, for clustered or recurrent events.
For instance :
-- ADDITIVE FRAILTY MODELS for proportional hazards models with two
correlated random effects (intercept random effect with random slope):
fitAdditive<-additivePenal(Surv(t1,t2,event)~cluster(group)+var1+slope(var1),
correlation=TRUE,data=dataAdditive,n.knots=8,kappa1=10000)
-- NESTED FRAILTY MODELS for hierarchically clustered data (with 2
levels of clustering) by including two random effects:
fitnested<-frailtyPenal(Surv(t1...
