abic.chen: Akaike information criterion (AIC) and Bayesian information criterion (BIC) for a sample from Chen distribution

Description

The function abic.chen() gives the loglikelihood, AIC and BIC values assuming Chen distribution with parameters beta and lambda. The function is based on the invariance property of the MLE.

Usage

abic.chen(x, beta.est, lambda.est)

Arguments

x

vector of observations

beta.est

estimate of the parameter beta

lambda.est

estimate of the parameter lambda

Value

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