# WEIBULL

### Definition of WEIBULL

Returns the value of the Weibull distribution function (or Weibull cumulative distribution function) for a specified shape and scale.

### Sample Usage

`WEIBULL(2.4, 2, 3, TRUE)`

`WEIBULL(A2,A3,A4,TRUE)`

### Syntax

`WEIBULL(x, shape, scale, [cumulative])`

`x`

- The input to the Weibull distribution function.`shape`

- The shape parameter of the Weibull distribution function.`shape`

is usually denoted k, and denoted as alpha in other spreadsheet packages.`shape`

must be greater than`0`

.

`scale`

- The scale parameter of the Weibull distribution function.`scale`

is usually denoted lambda in texts, and denoted as beta in other spreadsheet packages.`scale`

must be greater than`0`

.

`cumulative`

-`TRUE`

to use the cumulative distribution function,`FALSE`

to use the probability density function.

### Notes

- If
`shape`

is`1`

,`WEIBULL`

is equivalent to`EXPONDIST`

with`lambda`

set to`1/scale`

.
