Abstract. Xu and Cheung (2015, Stata Journal 15: 135–154) introduced the
strmcure command, which fits frailty models and frailty-mixture models in the
analysis of recurrent event times. In this article, we provide an update to strmcure.
The update implements a two-step estimation procedure for a frailty-mixture
model that allows the estimation of the effect of an intervention on the probability
of cure and on the total effect on event rate in the noncured. To illustrate, we
will use the same example dataset on respiratory exacerbations from the original
article.
