geary: Geary's test for normality

Description

This function computes an estimator of Geary's measure of kurtosis.

Usage

geary(x, na.rm = TRUE)

Arguments

x

the numeric vector.

na.rm

A logical for NA values.

Value

• statistic The Geary's test of statistic G.

  p.value The significant probability of the null-hypothesis testing.

encoding

UTF-8

Details

Null hypothesis is that the data obeys to normal distribution and that data should have kurtosis equal to 3.

Examples

set.seed(1234)
x = rnorm(1000)
geary(x)

geary(20:50)

y = c(0.269, 0.357, 0.2, 0.221, 0.275, 0.277, 0.253, 0.127, 0.246)
