BETADIST (Number,Alpha,Beta,LowerBound,UpperBound)


  • is the value between and
  • and are the value of the shape parameter
  • & the lower and upper limit to the interval of .
    • 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.
  • For e.g.,BETADIST(11..13,3,5,8,14)
  • BETADIST(33..35,5..6,10..11,30,40)


Examples

  1. =BETADIST(0.4,8,10) = 0.35949234293309396
  2. =BETADIST(3,5,9,2,6) = 0.20603810250759128
  3. =BETADIST(9,4,2,8,11) = 0.04526748971193415
  4. =BETADIST(5,-1,-2,4,7) = #N/A (ALPHA GREATER THAN (OR) NOT EQUAL TO 0)
