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
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 ≥ 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
