# BETA.INV

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

Returns the inverse of the cumulative probability function for a beta distribution.

 probability The probability associated with the distribution. alpha The parameter to the distribution. beta The parameter to the distribution. A (Optional) The lower bound to the interval of x. B (Optional) The upper bound to the interval of x.

 REMARKS
 * This function was added in Excel 2010 to replace the BETAINV function.* The beta distribution is a [[continuous distribution]]* If "A" is left blank, then 0 is used.* If "B" is left blank, then 1 is used* You can use the BETA.DIST to return the probability distribution function OR the cumulative distribution function for a beta distribution.* For the Microsoft documentation refer to support.microsoft.com* For the Google documentation refer to support.google.com
