spduration: Split-Population Duration (Cure) Regression

An implementation of split-population duration regression models. Unlike regular duration models, split-population duration models are mixture models that accommodate the presence of a sub-population that is not at risk for failure, e.g. cancer patients who have been cured by treatment. This package implements Weibull and Loglogistic forms for the duration component, and focuses on data with time-varying covariates. These models were originally formulated in Boag (1949) <http://www.jstor.org/stable/2983694> and Berkson and Gage (1952) <http://www.jstor.org/stable/2281318>, and extended in Schmidt and Witte (1989) <doi:10.1016/0304-4076(89)90034-1>.
