jb_bootstrap.test {nortsTest}

The Sieve Bootstrap Jarque-Bera test for normality.

Description

Performs the approximated Jarque Bera test of normality for univariate time series. Computes the p-value using Psaradakis and Vavra's (2020) sieve bootstrap procedure.

Usage

jb_bootstrap.test(y, reps = 1000, h = 100, seed = NULL)

Arguments

y

a numeric vector or an object of the ts class containing a stationary time series.

reps

an integer with the total bootstrap repetitions.

h

an integer with the first burn-in sieve bootstrap replicates.

seed

An optional seed to use.

Details

Employs Jarque Bera skewness-kurtosis test approximating the p-value using a sieve-bootstrap procedure, Psaradakis, Z. and Vávra, M. (2020).

Value

A list with class "h.test" containing the following components:

statistic:

the sieve bootstrap Jarque Bera's statistic.

p.value:

the p value for the test.

alternative:

a character string describing the alternative hypothesis.

method:

a character string “Sieve-Bootstrap Jarque Bera's test”.

data.name:

a character string giving the name of the data.
