Description Usage Arguments Details Value References Examples

View source: R/Kumaraswamy.R

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 and b and iterations it.

Usage

1
NegLLKumBin(x,freq,a,b,it=25000)

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

it

number of iterations to converge as a proper probability function replacing infinity

Details

0 < a,b

x = 0,1,2,...

freq ≥ 0

it > 0

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

Value

The output of NegLLKumBin will produce a single numeric value
