BetaINV() returns the inverse of the accumulated probability of the Beta distribution.
Syntax:
BetaInv(prob, alpha, beta)
Return data type: number
| Argument | Description |
|---|---|
| prob | A probability associated with the Beta-probability distribution. It must be a number between 0 and 1. |
| alpha | A positive number defining the first shape parameter. It is the exponent of the random variable |
| beta | A positive number defining the second shape parameter. It is the exponent that controls the shape of the distribution. |
This function is related
to the BetaDist function in the following way:
If prob = BetaDist(value, alpha, beta), then BetaInv(prob, alpha, beta) = value
