Representation of class cajo.test


Description

This class contains the relevant information by estimating and testing a VAR under linear restrictions on \bold{α} and \bold{β}.

Slots

Z0:

Object of class "matrix": The matrix of the differenced series.

Z1:

Object of class "matrix": The regressor matrix, except for the lagged variables in levels.

ZK:

Object of class "matrix": The matrix of the lagged variables in levels.

ecdet:

Object of class "character": Specifies the deterministic term to be included in the cointegration relation. This can be either "none", "const", or "trend".

H:

Object of class "ANY": The matrix containing the restrictions placed upon \bold{β}.

A:

Object of class "ANY": The matrix containing the restrictions placed upon \bold{α}.

B:

Object of class "ANY": The matrix orthogonal to matrix \bold{A}.

type:

Object of class "character": The test type.

teststat:

Object of class "numeric": The value of the test statistic.

pval:

Object of class "vector": The p-value and the degrees of freedom.

lambda:

Object of class "vector": The eigenvalues of the restricted model.

Vorg:

Object of class "matrix": The matrix of eigenvectors, such that \hat V_{…}'(H'S_{…}H)\hat V_{…} = I.

V:

Object of class "matrix": The matrix of the restricted eigenvectors, normalised with respect to the first variable.

W:

Object of class "matrix": The matrix of the corresponding loading weights.

PI:

Object of class "matrix": The coefficient matrix of the lagged variables in levels.

DELTA:

Object of class "ANY": The variance/covarinace matrix of \bold{V}.

DELTA.bb:

Object of class "ANY": The variance/covarinace matrix of the marginal factor \bold{B}'\bold{R}_{0t}.

DELTA.ab:

Object of class "ANY": The variance/covarinace matrix of the conditional distribution of \bold{A}'\bold{R}_{0t} and \bold{R}_{kt}.

DELTA.aa.b:

Object of class "ANY": The variance/covarinace matrix of the restricted loading matrix.

GAMMA:

Object of class "matrix": The coefficient matrix of \bold{Z1}.

test.name:

Object of class "character": The name of the test, i.e. ‘Johansen-Procedure’.
