BETAINV Function

Returns a quantile from the beta distribution.

Category: Quantile
Returned data type: DOUBLE

Syntax

BETAINV(p, a, b)

Arguments

p

is a numeric probability.

Range 0 ≤ p ≤ 1
Data type DOUBLE

a

is a numeric shape parameter.

Range a > 0
Data type DOUBLE

b

is a numeric shape parameter.

Range b > 0
Data type DOUBLE

Details

The BETAINV function returns the pth quantile from the beta distribution with shape parameters a and b. The probability that an observation from a beta distribution is less than or equal to the returned quantile is p.
Note: BETAINV is the inverse of the PROBBETA function.
