tweedieDistr: Tweedie Distribution

Provides density, distribution function, quantile function, and random generation for the Tweedie distribution under the compound Poisson-Gamma parameterisation with power parameter in (1, 2). The density is evaluated using the series expansion of Dunn and Smyth (2005) <doi:10.1007/s11222-005-4070-y>, implemented in C++ via 'Rcpp' and 'RcppArmadillo' for performance. A constructor compatible with the distributional package is also provided for use in tidy modelling workflows.

Version: 0.1.0
Depends: R (≥ 4.1.0)
Imports: distributional, Rcpp, rlang, stats
LinkingTo: Rcpp, RcppArmadillo
Suggests: ggdist, ggplot2, testthat (≥ 3.0.0), tibble, tweedie
