BETADISTX(x,alpha,beta)


  • 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.
2.  or  

Examples

  1. =BETADISTX(0.67,9,12) = 0.3102416743686678
  2. =BETADISTX(6,34,37) = 2.576888446568541e+72
  3. =BETADISTX(100,456,467)= NaN
