BETAINV (Probability,Alpha,Beta,LowerBound,UpperBound,Accuracy,DivisionsAndDepthArray)


  • is the probability value associated with the beta distribution.
  • & are the values of the shape parameter.
  • & the lower and upper limit to the interval of .

Description

  • This function gives the inverse value of Cumulative Beta Probability Distribution.
  • It is called Inverted Beta Function or Beta Prime.
  • In , is the probability value associated with Beta Distribution, and are the values of two positive shape parameters and and are the lower and upper limit.
  • Normally the limit values are optional, i.e. when we are giving the values of & then the result value is from and .
  • When we are omitting the values and , by default it will consider and , so the result value is from and .
  • If , then .
  • use the iterating method to find the value of .suppose the iteration has not converged after 100 searches, then the function gives the error result.
  • This function will give the error result when
1.Any one of the arguments are non-numeric
2.Alpha or Beta  0 
3.Number<LowerBound ,Number>UpperBound or LowerBound = UpperBound
4.we are not mentioning the limit values  for LowerBound & UpperBound , 
  by default it will consider the Standard Cumulative Beta Distribution, LowerBound = 0 and UpperBound = 1

ZOS

  • The syntax is to calculate of this function in ZOS is .
    • is the probability value associated with the beta distribution.
    • and are the values of the shape parameter.
    • For e.g.,BETAINV(0.30987,10,18,12,16)

Examples

  1. BETAINV(0.2060381025,5,9,2,6) = 3
  2. BETAINV(0.359492343,8,10) = 1.75
  3. BETAINV(0.685470581,5,8,2,6) = 3.75
  4. BETAINV(0.75267,1,7,7,9) = 7.25
  5. BETAINV(0.5689,-2,4,3,5) = NAN, because .
