• BETADIST(),returns the Beta Cumulative Distribution Function.

## 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 the value between and .
• Alpha is the value of the shape parameter.
• Beta is the value of the shape parameter
• and (optional) are the Lower and Upper limit to the interval of .
• Normally lies between the limit and , suppose when we are omitting and value, by default value with in 0 and 1.
• 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.
2. or
3. ,, or

• we are not mentioning the limit values and ,
• By default it will consider the Standard Cumulative Beta Distribution, LowerBound = 0 and UpperBound = 1.

## ZOS

• The syntax is to calculate BEATDIST in ZOS is .
• is the value between LowerBound and UpperBound
• and are the value of the shape parameter.
