BETA.DIST function: Description, Usage, Syntax, Examples and Explanation
What is BETA.DIST function in Excel?
Syntax of BETA.DIST function
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.
BETA.DIST formula explanation
- 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
