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

1
NegLLMcGBB(x,freq,a,b,c)

Arguments

x

vector of binomial random variables

freq

vector of frequencies

a

single value for shape parameter alpha representing as a

b

single value for shape parameter beta representing as b

c

single value for shape parameter gamma representing as c

Details

0 < a,b,c

freq ≥ 0

x = 0,1,2,...

Value

The output of NegLLMcGBB will produce a single numeric value
