lb.test: The Ljung-Box Test for Uncorrelated Data

In spgs: Statistical Patterns in Genomic Sequences

The Ljung-Box Test for Uncorrelated Data

Description

This function is a convenient wrapper for using Box.test to perform the Ljung- Box Q test of uncorrelated data without having to specify ‘⁠type⁠’. In other words, lb.test(x, ...) is equivalent to Box.test(x, type="Ljung-Box", ...).

Usage

lb.test(x, ...)

Arguments

x	a numeric vector or univariate time series.
...	parameters to pass to Box.test.

Value

A list with class "htest" containing the following components:

statistic	the value of the test statistic.
parameter	the degrees of freedom of the approximate chi-squared distribution of the test statistic (taking fitdf into account).
p.value	the p-value of the test.
method	a character string indicating what type of test was performed.
data.name	a character string giving the name of the data.
