abic.log.gamma: Akaike information criterion (AIC) and Bayesian information criterion (BIC) for log-gamma(LG) distribution

Description

The function abic.log.gamma() gives the loglikelihood, AIC and BIC values assuming an log-gamma(LG) distribution with parameters alpha and lambda.

Usage

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