norm.1980JB: Univariate Test of Normality by Jarque and Bera (1980)

Description

Given an univariate sample \(x\), it tests $$H_0 : x\textrm{ is from normal distribution} \quad vs\quad H_1 : \textrm{ not } H_0$$ using a test procedure by Jarque and Bera (1980).

Usage

norm.1980JB(x, method = c("asymptotic", "MC"), nreps = 2000)

Value

a (list) object of S3 class htest containing:

statistic

a test statistic.

p.value

\(p\)-value under \(H_0\).

alternative

alternative hypothesis.

method

name of the test.

data.name

name(s) of provided sample data.

Arguments

x

a length-\(n\) data vector.

method

method to compute \(p\)-value. Using initials is possible, "a" for asymptotic for example. Case insensitive.

nreps

the number of Monte Carlo simulations to be run when method="MC".

Examples

## generate samples from uniform distribution
x = runif(28)

## test with both methods of attaining p-values
test1 = norm.1980JB(x, method="a") # Asymptotics
test2 = norm.1980JB(x, method="m") # Monte Carlo
