• is any real number.
• alpha and beta are the value of the shape parameter

## Description

• This function gives the Cumulative Beta Probability Density function.
• The beta distribution is a family of Continuous Probability Distributions defined on the interval [0, 1] parameterized by two positive shape parameters, denoted by and .
• The Beta Distribution is also known as the Beta Distribution of the first kind.
• In , is any real number.
• alpha is the value of the shape parameter.
• beta is the value of the shape parameter
• The Probability Density Function of the beta distribution is:

where ; and is the Beta function.

• The formula for the Cumulative Beta Distribution is called the Incomplete Beta function ratio and it is denoted by and is defined as :

=, where  ; and is the Beta function.

• This function will give the result as error when
1.Any one of the arguments are non-numeric.
