I want to compare the risk of dying of a specific cancer versus "other causes" in a large sample. Compare reason a versus b. I am trying to use stcrreg command but it requires covariables in the model, which I don't want to include. Is it possible to run this command without covariables? Is there a specific setting up that permits comparing two risks without covariables? When not entering covariables, it results in an empty model.
Thanks
