Syntax
expression.BetaDist(Arg1, Arg2, Arg3, Arg4, Arg5)
expression A variable that represents a WorksheetFunction object.
Parameters
| Name | Required/Optional | Data Type | Description |
|---|---|---|---|
| Arg1 | Required | Double | The value between A and B at which to evaluate the function. |
| Arg2 | Required | Double | A parameter of the distribution. |
| Arg3 | Required | Double | A parameter of the distribution. |
| Arg4 | Optional | Variant | An optional lower bound to the interval of x. |
| Arg5 | Optional | Variant | An optional upper bound to the interval of x. |
Return Value
Double
Remarks
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.
- If any argument is nonnumeric, BetaDist returns the #VALUE! error value.
- If alpha ≤ 0 or beta ≤ 0, BetaDist generates an error value.
- If x < A, x > B, or A = B, BetaDist generates an error value.
- If you omit values for A and B, BetaDist uses the standard cumulative beta distribution, so that A = 0 and B = 1.
