In urca: Unit Root and Cointegration Tests for Time Series Data

Likelihood ratio test for restrictions under partly known beta

Description

This function estimates a restricted VAR, where some of the cointegration vectors are known. The known cointegration relationships have to be provided in an p x r1 matrix \bold{H}. The test statistic is distributed as \chi^2 with (p-r)r1 degrees of freedom, with r equal to total number of cointegration relations.

Usage

bh5lrtest(z, H, r)

Arguments

z	An object of class ca.jo.
H	The (p \times r1) matrix containing the known cointegration relations.
r	The count of cointegrating relationships; inferred from summary(ca.jo-object).

Details

Please note, that the number of columns of \bold{H} must be smaller than the count of cointegration relations r.

Value

An object of class cajo.test.
