%description
Implements Random Forest regression under the Power Xgamma distribution
error model. Provides core distribution functions (density, cumulative
distribution, quantile, random generation, hazard, survival), parameter
estimation via Expectation-Maximization (EM) and Markov Chain Monte Carlo
(MCMC), non-parametric bootstrap confidence intervals (at 90%%, 95%%, and
99%% levels), Highest Posterior Density (HPD) intervals, Heidelberger and
Welch's MCMC convergence diagnostic, convergence probability, model
evaluation metrics (estimated values, bias, mean squared error, risk
value), homoscedastic prediction intervals, and goodness-of-fit diagnostic
tests (Kolmogorov-Smirnov and Anderson-Darling tests, Akaike Information
Criterion, and Bayesian Information Criterion). References: Tyagi et al.
