NegLLBetaBin function

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.

Details

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

Examples

No.D.D <- 0:7 #assigning the random variables Obs.fre.1 <- c(47,54,43,40,40,41,39,95) #assigning the corresponding frequencies NegLLBetaBin(No.D.D,Obs.fre.1,.3,.4) #acquiring the negative log likelihood value
