Abstract

stcrmix fits competing risk models through mixtures of generalized gamma distributions, using maximum likelihood, according to methods in Checkley, Brower and Munoz (Epidemiology 2010). This command allows for the specification of two competing risk events, along with a category for individuals for whom the event type was unobserved. Moreover, an upper censoring time should be specified. This is assumed to be the latest potential time at which an individual would be expected to develop one event or the other which is content dependent but if unknown, user can select the times corresponding to when individuals will reach 125 years of age. In terms of parameters, this model allows for seven components of parameters to be estimated, including one for the proportion of subjects that achieve each competing risk, and then three parameters for the distribution of times to each competing risk (location, scale and shape).
