Share:

Description

The function abic.flex.weibull() gives the loglikelihood, AIC and BIC values assuming an flexible Weibull(FW) distribution with parameters alpha and beta.

Usage

1
abic.flex.weibull(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.flex.weibull() gives the loglikelihood, AIC and BIC values.
