NegLLMultiBin {fitODBOD}

Negative Log Likelihood value of Multiplicative Binomial distribution

Description

This function will calculate the negative log likelihood value when the vector of binomial random variable and vector of corresponding frequencies are given with the input parameters.

Usage

NegLLMultiBin(x,freq,p,theta)

Arguments

x

vector of binomial random variables.

freq

vector of frequencies.

p

single value for probability of success.

theta

single value for theta parameter.

Details

freq \ge 0

x = 0,1,2,..

0 < p < 1

0 < theta

Value

The output of NegLLMultiBin will produce a single numeric value.
