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 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
.
