Z |

number of endogenous variables, the remaining variables will be tested for weak exogeneity |
p |
lag order of the endogenous variables |
q |
lag order of the weakly exogenous variables |

intercept and trend options from |
In order to be weakly exogenous variables X must be (a) integrated of order 1 (X~I(1)); it follows (b) that X is not cointegrated on its own, and (c) that the differenced process does not depend on the lagged Z.
The variables tested will be the variables from the last (N-n) columns of the matrix Z
, where N is the total number of columns.
Results for test (a) to (c).
