Compatibility - BETADIST Function
The BETADIST function replaces the BETA.DIST function from Excel 2010.
Description
This function returns the cumulative beta probability density function. The beta distribution is commonly used to study variation in the percentage of something across samples.
Syntax
BETADIST(x,alpha,beta,[A],[B])
Arguments
Argument | Description | Required/ Optional |
---|---|---|
X | The value between A and B at which to evaluate the function. | Required |
Alpha | A parameter of the distribution. | Required |
Beta | A parameter of the distribution. | Required |
A | A lower bound to the interval of x. | Optional |
B | An upper bound to the interval of x. | Optional |
Notes
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
