BETADIST

MS Excel Spreadsheet

See Also

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

Syntax

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

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

Alpha    is a parameter to the distribution.

Beta    is a parameter to the distribution.

A    is an optional lower bound to the interval of x.

B    is an optional 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.

Example

The example may be easier to understand if you copy it to a blank spreadsheet.
