Tsay's test

Description

Tsay's test: test for nonlinearity against the null hypothesis that the time series follows some AR process. This is a generalization of Keenan's test.

Usage

tsayTest(time.series, order)

Arguments

time.series

The original time.series.

order

Order used for the AR model.

A list containing the results of the test, including:

• test.stat: the F-squared test statistic

• p.value.

• order: order of the AR process used for testing.
