''A note on testing parameter constancy in cointegrated vector autoregression: the case of near I(2) processes'' |
( 2009, Vol. 29 No.2 ) |
|
|
This note investigates the behaviour of a parameter-constancy test statistic when near I(2) (integrated of order 2) variables are incorporated in a cointegrated vector autoregressive system. Simulation studies indicate that the presence of such variables has a significant impact on size properties of the constancy test. |
