The Power of the KPSS–Test for Cointegration when Residuals are Fractionally Integrated |
We show that the power of the KPSS-test against integration, as measured by divergence rates of the test statistic under the alternative, remains the same when residuals from an OLS-regression rather than true observations are used. The divergence rate is independent of the order of integration of the cointegrating regressors which are allowed to be I(1 + dX) in out set up. |
