dMultiBin function

Multiplicative Binomial Distribution

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

dMultiBin(x,n,p,theta)

Arguments

• x: vector of binomial random variables.
• n: single value for no of binomial trials.
• p: single value for probability of success.
• theta: single value for theta.

Returns

The output of dMultiBin gives a list format consisting

pdf probability function values in vector form.

mean mean of Multiplicative Binomial Distribution.

var variance of Multiplicative Binomial Distribution.

Details

The probability function and cumulative function can be constructed and are denoted below

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

here $f(p,theta,n)$ is

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