EstMLEKumBin: Estimating the shape parameters a and b and iterations for Kumaraswamy Binomial Distribution

Description

The function will estimate the shape parameters using the maximum log likelihood method for the Kumaraswamy Binomial distribution when the binomial random variables and corresponding frequencies are given

Usage

EstMLEKumBin(x,freq,a,b,it)

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.

Value

EstMLEKumBin here is used as a input parameter for the mle2 function of bbmle package therefore output is of class of mle2.

Details

$$0 < a,b$$ $$x = 0,1,2,...$$ $$freq \ge 0$$ $$it > 0$$

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