dew	R Documentation

Exponentiated Weibull pdf

Description

Computes the pdf of the exponentiated Weibull distribution

Usage

dew(x, alpha = 1, c = 1, lambda = 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
`c`	the value of c parameter, must be positive
`lambda`	the value of lambda 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. This function uses the R contributed package reliaR.
