NegLLGHGBB: Negative Log Likelihood value of Gaussian Hypergeometric...

In fitODBOD: Modeling Over Dispersed Binomial Outcome Data Using BMD and ABD

Negative Log Likelihood value of Gaussian Hypergeometric Generalized Beta Binomial Distribution

Description

This function will calculate the negative log likelihood value when the vector of binomial random variables and vector of corresponding frequencies are given with the shape parameters a,b and c.

Usage

NegLLGHGBB(x,freq,a,b,c)

Arguments

x	vector of binomial random variables.
freq	vector of frequencies.
a	single value for shape parameter alpha representing a.
b	single value for shape parameter beta representing b.
c	single value for shape parameter lambda representing c.

Details

0 < a,b,c

freq \ge 0

x = 0,1,2,...

NOTE : If input parameters are not in given domain conditions necessary error messages will be provided to go further.

Value

The output of NegLLGHGBB will produce a single numeric value.
