Flexible Weibull pdf

Description

Computes the pdf of the flexible Weibull distribution

Usage

dfw(x, alpha = 1, beta = 1)

Arguments

x

scale or vector of positive values at which the pdf needs to be computed

alpha

the value of alpha parameter, must be positive

beta

the value of beta parameter, must be positive

Value

An object of the same length as x, giving the pdf values computed at x

Note

If incorrect values are input for x or the model parameters then NaNs will be returned as the output.
