In dtgiw: Discrete Transmuted Generalized Inverse Weibull Distribution

The probability mass function (PMF) for Discrete Transmuted Generalized Inverse Weibull (DTGIW) distribution.

Description

This function calculated the PMF of the DTGIW distribution.

Usage

dDTGIW(x, alpha, beta, lambda, theta, log = FALSE)

Arguments

x	vector of quantiles.
alpha	shape parameter#1.
beta	scale parameter.
lambda	shape pameter#2.
theta	the transmuted parameter.
log	logical(TRUE or FALSE); if log=FALSE, then return the PMF; if log=TRUE, then return the natural logarithms of the PMF.

Details

The PMF of the DTGIW distribution is shown in Theorem 1 based on the research paper in references.

Value

the PMF of DTGIW distribution
