Weibull {gestate} | R Documentation |
Weibull Curve constructor function
Description
This creates a Curve object for a Weibull distribution.
Curve objects contain all necessary information to describe a distribution, including functions and parameters describing it.
Parameterisation follows that used by pweibull etc. See Details for more information on parameterisation.
Usage
Weibull(alpha, beta = 1)
Arguments
alpha |
Scale parameter for Weibull distribution. |
beta |
Shape parameter for Weibull distribution. Default is 1; an exponential distribution. |
Details
The Weibull distribution with shape parameter beta and scale parameter alpha has parameterisation:
f(x) = (beta/alpha) (x/alpha)^(beta-1) exp(- (x/alpha)^beta)
F(x) = 1 - exp(- (x/alpha)^beta)
