%description
Fits mixture cure rate models by the Expectation-Maximization (EM)
algorithm. The incidence component (the probability of being uncured)
accepts the logit, probit, cauchit, power logit and reversed power logit
link functions, and the latency component accepts the exponential,
Rayleigh, Weibull, log-normal, log-logistic and inverse Gaussian
distributions. The package provides parameter estimates with standard
errors, simulation of data from the model, and diagnostic tools based on
residuals and simulated envelopes. The methods build on Berkson and Gage
(1952) <doi:10.2307/2281318>, Dempster, Laird and Rubin (1977)
<doi:10.1111/j.2517-6161.1977.tb01600.x> and Bazán, Torres-Avilés, Suzuki
and Louzada (2017) <doi:10.1002/asmb.2215>.
