BETA.INV Function

The BETA.INV function is one of the statistical functions. It is used to return the inverse of the beta cumulative probability density function (BETA.DIST).

The BETA.INV function syntax is:

BETA.INV(probability, alpha, beta, [,[A] [,[B]])

where

probability is a probability associated with the beta distribution. A numeric value greater than 0 and less than or equal to 1.

alpha is the first parameter of the distribution, a numeric value greater than 0.

beta is the second parameter of the distribution, a numeric value greater than 0.

A is the lower bound to the interval of x. It is an optional parameter. If it is omitted, the default value of 0 is used.

B is the upper bound to the interval of x. It is an optional parameter. If it is omitted, the default value of 1 is used.

The values can be entered manually or included into the cells you make reference to.

To apply the BETA.INV function,

1. select the cell where you wish to display the result,
2. click the Insert function
   icon situated at the top toolbar,
   or right-click within a selected cell and select the Insert Function option from the menu,
   or click the
   icon situated at the formula bar,
3. select the Statistical function group from the list,
