log_dagum {bayesCureRateModel}

PDF and CDF of the Dagum distribution

Description

The Dagum distribution as evaluated at the VGAM package.

Usage

log_dagum(y, a1, a2, a3, c_under = 1e-09)

Arguments

y

observed data

a1

scale parameter

a2

shape1.a parameter

a3

shape2.p parameter

c_under

A small positive value corresponding to the underflow threshold, e.g. c_under = 1e-9.

Details

The Dagum distribution is a special case of the 4-parameter generalized beta II distribution.

Value
