parfm unable to fit models when hazard rate is small
...for weibull, I set rho = 1 so it reduces to an exponential hazard, with rate = lambda # Also note sigma = 0, so random effect is not present ## Create data and fit model, lambda = 0.1 data0<-simulWeib(10000,lambda=0.1,rho=1,rateC=0.0000000001, beta1=0.25,beta2=0,beta3=0,beta4=0, sigma = 0) fit.cox0<-parfm(Surv(time,status) ~ x1, data=data0, dist="exponential") fit.cox0 ## Create data and fit model, lambda = 0.01 data0<-simulWeib(10000,lambda=0.01,rho=1,rateC=0.0000000001, beta1=0.25,beta2=0,beta3=0,beta4=0, sigma = 0) fit.cox0<-parfm(Surv(time,status) ~ x1, data=data0, dis...
