HiddenTrunc - Hidden Truncation Probability Distributions and Statistical Inference

Probability functions, random generation, likelihood-based inference, diagnostics, simulation, and Bayesian computation for probability models generated through hidden truncation. The initial release implements the upper-hidden-truncated Pareto type IV model and the two-sided hidden-truncated Arnold-Strauss bivariate exponential model, together with a generic hidden-truncation engine.
