thr.test: Threshold Nonlinearity Test

In ConvFuncTimeSeries/test3:

Description

Threshold nonlinearity test.

Usage

thr.test(y, p = 1, d = 1, thrV = NULL, ini = 40, include.mean = T)

Arguments

y	a time seris.
p	AR order.
d	delay for the threhosld variable.
thrV	threshold variable.
ini	inital number of data to start RLS estimation.
include.mean	a logical value for including constant terms.

Value

thr.test returns a list with components:

F-ratio	F statistic.
df	the numerator and denominator degrees of freedom.
ini	initial number of data to start RLS estimation.
