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]])
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,
- select the cell where you wish to display the result,
- 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,
- select the Statistical function group from the list,
- click the BETA.INV function,
- enter the required arguments separating them by commas,
