I'm not sure what the muhaz function is (it's not in the survival package), but regardless, unless I'm seriously mistaken, there's no information to estimate the hazard function if you haven't observed any events.
I hope that this helps, John

Dear All,
I would like to ask if it is possible to estimate a hazard function using the muhaz command when all the data is right-censored. My data has information of the number of weeks people has been unemployed but all of them are unemployed at the date of the survey, that is, I cannot observed when the individuals leave the unemployment state.
I appreciate your help,
Best,
Monica L.
