BETA.DIST

Definition

Returns the beta distribution.

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

BETA.DIST(x,alpha,beta,cumulative,[A],[B])

The BETA.DIST 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.

• Cumulative      Required. A logical value that determines the form of the function. If cumulative is TRUE, BETA.DIST returns the cumulative distribution function; if FALSE, it returns the probability density function.

• 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, BETA.DIST returns the #VALUE! error value.

• If alpha ≤ 0 or beta ≤ 0, BETA.DIST returns the #NUM! error value.

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

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