abic.lfr: Akaike information criterion (AIC) and Bayesian information criterion (BIC) for linear failure rate(LFR) distribution

Description

The function abic.lfr() gives the loglikelihood, AIC and BIC values assuming an linear failure rate(LFR) distribution with parameters alpha and beta.

Usage

abic.lfr(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.lfr() gives the loglikelihood, AIC and BIC values.
