Syntax
WEIBULLDIST( <number>;<number>;< number >;<boolean>)
Description
Returns the weibull distribution for a certain value with given alpha and beta.
or
Returns the weibull density function or the cumulative distribution function for the weibull distribution. This function is frequently used used to measure the degree of diversity between two data sets.
The function arguments are:
- x: The value for which the distribution should be computed (NUMERIC)
- Alpha: The alpha parameter of the distribution (NUMERIC)
- Beta: The beta parameter of the distribution (NUMERIC)
- Cumulative: Constant indicating the form of the function. If "true" then the cumulative distribution function is used. If "false" then the probability mass function is used. (BOOLEAN)
| Cumulative/Boolean | Logical argument which defines the type of distribution to be calculated |
|---|---|
| True | Uses the cumulative distribution function |
| False | Uses the probability density function |
Example
WEIBULLDIST(#input!Value;#input!Alpha;#input!Beta;cumulative value)
Value | Alpha | Beta | Cumulative value | WEIBULLDIST returns |
|---|---|---|---|---|
| 105 | 20 | 100 | false | 0.035589 |
| 105 | 20 | 100 | false | 0.929581 |
Common Errors
| #NUM! | - | Occurs if either:
|
| #VALUE! | - | Occurs if the argument type isn't numeric |
