blrtest: Likelihood ratio test for restrictions on beta

Description

This function estimates a restricted VAR, where the restrictions are base upon $\text{bold}\beta$, i.e. the cointegration vectors. The test statistic is distributed as ${\chi }^2$ with $r(p-s)$ degrees of freedom, with $s$ equal to the columns of the restricting matrix $\text{bold}H$.

Usage

blrtest(z, H, r)

Value

An object of class cajo.test.

Arguments

z

An object of class ca.jo.

H

The $(p\times s)$ matrix containing the restrictions on $\text{bold}\beta$.

r

The count of cointegrating relationships;
inferred from summary(ca.jo-object).

Details

Please note, that in the case of nested hypothesis, the reported p-value should be adjusted to $r(s1-s2)$ (see Johansen, S. and K. Juselius (1990)).
