%description
Provides an implementation of finite mixture regression models for
censored data under four distributional families: Normal (FM-NCR), Student
t (FM-TCR), skew-Normal (FM-SNCR), and skew-t (FM-STCR). The package
enables flexible modeling of skewness and heavy tails often observed in
real-world data, while explicitly accounting for censoring. Functions are
included for parameter estimation via the Expectation-Maximization (EM)
algorithm, computation of standard errors, and model comparison criteria
such as the Akaike Information Criterion (AIC), the Bayesian Information
Criterion (BIC), and the Efficient Determination Criterion (EDC). The
underlying methodology is described in Park et al. (2024)
<doi:10.1007/s00180-024-01459-4>.
