NegLLBetaCorrBin: Negative Log Likelihood value of Beta-Correlated Binomial...

In Amalan-ConStat/R-fitODBOD: Modeling Over Dispersed Binomial Outcome Data Using BMD and ABD

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 input parameters.

Usage

NegLLBetaCorrBin(x,freq,cov,a,b)

Arguments

x	vector of binomial random variables.
freq	vector of frequencies.
cov	single value for covariance.
a	single value for alpha parameter.
b	single value for beta parameter.

Details

freq ≥ 0

x = 0,1,2,..

-∞ < cov < +∞

0 < a,b

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

Value

The output of NegLLBetaCorrBin will produce a single numeric value.
