pUniBin: Uniform Binomial Distribution

In fitODBOD: Modeling Over Dispersed Binomial Outcome Data Using BMD and ABD

Uniform Binomial Distribution

Description

These functions provide the ability for generating probability function values and cumulative probability function values for the Uniform Binomial Distribution.

Usage

pUniBin(x,n)

Arguments

x	vector of binomial random variables.
n	single value for no of binomial trials.

Details

Mixing unit bounded uniform distribution with binomial distribution will create the Uniform Binomial Distribution. The probability function and cumulative probability function can be constructed and are denoted below.

The cumulative probability function is the summation of probability function values.

P_{UniBin}(x)= \frac{1}{n+1}

n = 1,2,...

x = 0,1,2,...n

The mean, variance and over dispersion are denoted as

E_{UniBin}[X]= \frac{n}{2}

Var_{UniBin}[X]= \frac{n(n+2)}{12}

over dispersion= \frac{1}{3}

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

Value

The output of pUniBin gives cumulative probability function values in vector form.
