sglg (version 0.2.2)

gnfit: gnfit

Description

This function provides some useful statistics to assess the quality of fit of generalized log-gamma probabilistic model, including the statistics Cramer-von Mises and Anderson-Darling. It can also calculate other goodness of fit such as Hannan-Quin Information Criterion and Kolmogorov-Smirnov test.

Usage

gnfit(starts, data)

Arguments

starts

numeric vector. Initial parameters to maximize the likelihood function

data

numeric vector. A sample of a generalized log-gamma distribution.

Examples

if (FALSE) {
set.seed(1)
# The size of the sample must be median or large to obtain a good estimates
n <- 100
sample <- rglg(n,location=0,scale=0.5,shape=0.75)
# This step takes a few minutes.
result <- gnfit(starts=c(0.1,0.75,1),data=sample)
result
}
