BETA.INV

  • Article

Applies to: Calculated column Calculated table Measure Visual calculation

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])

Parameters

Term Definition
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 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.

  • This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.
