Wald Tests of I(1) against I(d) alternatives: some new properties and an extension to processes with trending components [PDF]
, 2007 Forthcoming 2008This paper analyses the behaviour of a Wald-type test, i.e., the (E¢ cient) Fractional Dickey-Fuller (EFDF) test of I(1) against I(d); d < 1; relative to LM tests. Further, it extends the implementation of the EFDF test to the presence of
