%description
Tools to fit Mixture Cure Rate models via the Expectation-Maximization
(EM) algorithm, allowing for flexible link functions in the cure component
and various survival distributions in the latency part. The package
supports user-specified link functions, includes methods for parameter
estimation and model diagnostics, and provides residual analysis tailored
for cure models. The classical theory methods used are described in
