[!INCLUDEapplies-to-measures-columns-tables-visual-calculations]
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.
BETA.INV(probability,alpha,beta,[A],[B])
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. |
Returns the inverse of the beta cumulative probability density function (BETA.DIST).
-
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.
