PBGoF: Goodness-of-Fit Tests for Skew-Normal and Skew-t Models
Provides precomputed-quantile goodness-of-fit tests for skew-normal distributions, parametric-bootstrap tests for skew-normal and skew-t distributions, robust fitting, and graphical diagnostics. Package methods and documentation are described by Li, Xu, and Khang (2026) <https://github.com/Divo-Lee/PBGoF>.
