Generate EVBS Density Values

Computes \((t, f(t))\) pairs of the Extreme-Value Birnbaum-Saunders (EVBS) density over its support, for given parameters.

Usage

generate_evbs_data(alpha, beta, gama)

Arguments

alpha

Shape parameter \(\alpha > 0\).

beta

Scale parameter \(\beta > 0\).

gama

Tail-shape parameter \(\gamma\) (real). The support is bounded below when \(\gamma > 0\) and above when \(\gamma < 0\).

Value

A data.frame with columns t (support points) and y (density values).
