BETAINV(prob,alpha,beta,a,b)
- 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. or 3. or 4.we are not mentioning the limit values for &, by default it will consider the Standard Cumulative Beta Distribution, and .
Examples
- BETAINV(0.2060381025,5,9,2,6) = 3
- BETAINV(0.359492343,8,10) = 1.75
- BETAINV(0.685470581,5,8,2,6) = 3.75
- BETAINV(0.75267,1,7,7,9) = 7.25
- BETAINV(0.5689,-2,4,3,5) = NAN, because .
