# abic.gp.weibull: Akaike information criterion (AIC) and Bayesian information... In reliaR: Package for some probability distributions.

## Description

The function `abic.gp.weibull()` gives the `loglikelihood`, `AIC` and `BIC` values assuming an generalized power Weibull(GPW) distribution with parameters alpha and theta.

## Usage

 `1` ```abic.gp.weibull(x, alpha.est, theta.est) ```

## Arguments

 `x` vector of observations `alpha.est` estimate of the parameter alpha `theta.est` estimate of the parameter theta

## Value

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