Note: BETADIST is supplemented by the new function BETA.DIST with additional functionality, which is available in newer versions of Microsoft Excel (2010 or later).
Syntax:
BETADIST(X, Alpha, Beta [, A, B])
Description:
This returns the beta cumulative distribution function.
X is the value whose probability is to be calculated.
Alpha and Beta are shape parameters of the function. They both have to be greater than zero.
A and B (optional) determine the limits of the interval for X. If they are omitted, A is set to 0 and B is set to 1 (thus leading to a normal distribution).
X must be in the range A to B.
