In reliaR: Package for some probability distributions.

Description

The function abic.weibull.ext() gives the loglikelihood, AIC and BIC values assuming an Weibull Extension(WE) distribution with parameters alpha and beta.

Usage

abic.weibull.ext(x, alpha.est, beta.est)

Arguments

x	vector of observations
alpha.est	estimate of the parameter alpha
beta.est	estimate of the parameter beta

Value

The function abic.weibull.ext() gives the loglikelihood, AIC and BIC values.
