Returns the cumulative beta probability density function. The beta distribution is commonly used to study variation in the percentage of something across samples, such as the fraction of the day people spend watching television.

Sample Usage

Syntax

BETADIST(x,alpha,beta,[A],[B])

The BETADIST function syntax has the following arguments:

X Required. The value between A and B at which to evaluate the function.

Alpha Required. A parameter of the distribution.

Beta Required. A parameter of the distribution.

A Optional. A lower bound to the interval of x.

B Optional. An upper bound to the interval of x.

Remarks

If any argument is nonnumeric, BETADIST returns the #VALUE! error value.

If alpha ≤ 0 or beta ≤ 0, BETADIST returns the #NUM! error value.

If x < A, x > B, or A = B, BETADIST returns the #NUM! error value.

If you omit values for A and B, BETADIST uses the standard cumulative beta distribution, so that A = 0 and B = 1.
