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 than0
.
-
-
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 than0
.
-
-
cumulative
-TRUE
to use the cumulative distribution function,FALSE
to use the probability density function.
Notes
- If
shape
is1
,WEIBULL
is equivalent toEXPONDIST
withlambda
set to1/scale
.
