abic.moew: Akaike information criterion (AIC) and Bayesian information criterion (BIC) for the Marshall-Olkin Extended Weibull(MOEW) distribution

Description

The function abic.moew() gives the loglikelihood, AIC and BIC values assuming an MOEW distribution with parameters alpha and lambda.

Usage

abic.moew(x, alpha.est, lambda.est)

Arguments

x

vector of observations

alpha.est

estimate of the parameter alpha

lambda.est

estimate of the parameter lambda

Value

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