WEIBULLReturns 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.
