Matched-moments distribution comparison plot

Solves for the parameters of each distribution family such that all curves share the same mean and coefficient of variation (CV) as the reference Gamma scenario (mu0\,=\,2, phi\,=\,3.5). The resulting PDFs are plotted on a faceted panel so that differences in distributional shape — tail heaviness, skewness, modality — are visible even when the first two moments are identical.

Usage

generate_matched_moments_plot(burr_kappas = 2, gg_kappas = c(0.5, 1.5))

Arguments

burr_kappas

Numeric vector of kappa (k) values for Burr XII curves. Default: c(2, 3, 5).

gg_kappas

Numeric vector of Q values for the generalised gamma curves. Default: c(0.1, 0.5, 1.0, 2.0, 3.0).

Value

A ggplot object.
