Negative Log Likelihood value of Beta-Binomial Distribution
Negative Log Likelihood value of Beta-Binomial Distribution
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 and b.
NegLLBetaBin(x,freq,a,b)
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.
Returns
The output of NegLLBetaBin will produce a single numeric value.
