Hello, Is it possible to create confidence intervals for hazard rates? I'm creating two muhaz objects:
haz1 <- muhaz(NumDaysCustomer[cRV=="true"],status[cRV=="true"]) haz2 <- muhaz(NumDaysCustomer[cRV=="false"],status[cRV=="false"]) and plotting them. There are many, many more observations in the cohort cRV=="false" than =="true". And, there are many more observations with lifetimes in the middle of the range than at the ends. I suspect that this is a common phenomenon. When I plot the two hazard rate curves, haz1 looks very different than haz2, but I'd like to see if it's different enough. How can I go about creating confidence intervals and plotting them?
