lobato_bootstrap.test {nortsTest}

The Sieve Bootstrap Lobato and Velasco's Test for normality.

Description

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

Usage

lobato_bootstrap.test(y, c = 1, reps = 1000, h = 100, seed = NULL)

Arguments

y

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

c

a positive real value that identifies the total amount of values used in the cumulative sum.

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

This test proves a normality assumption in correlated data employing the skewness-kurtosis test statistic proposed by Lobato, I., & Velasco, C. (2004), 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 Lobato n Velasco's statistic.

p.value:

the p value for the test.

alternative:

a character string describing the alternative hypothesis.

method:

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

data.name:

a character string giving the name of the data.
