BETA.INV DAX Function (Statistical)

Returns the inverse of the beta cumulative probability density function (BETA.DIST). If probability = BETA.DIST(x,…TRUE), then BETA.INV(probability,…) = x. The beta distribution can be used in project planning to model probable completion times given an expected completion time and variability.

Syntax

BETA.INV ( <Probability>, <Alpha>, <Beta> [, <A>] [, <B>] )
Parameter Attributes Description
Probability

A probability associated with the beta distribution.

Alpha

A parameter of the distribution.

Beta

A parameter the distribution.

A Optional

A lower bound to the interval of x.

B Optional

An upper bound to the interval of x.

Return values

Scalar A single decimal value.

Returns the inverse of the beta cumulative probability density function (BETA.DIST).

Remarks

If any argument is nonnumeric, BETA.INV returns the #VALUE! error value.

If any argument is not an integer, it is rounded.

If alpha ≤ 0 or beta ≤ 0, BETA.INV returns the #NUM! error value.

If probability ≤ 0 or probability > 1, BETA.INV returns the #NUM! error value.

If you omit values for A and B, BETA.INV uses the standard cumulative beta distribution, so that A = 0 and B = 1.
