The new testsre proposed to eschew the downward weighting problem of the traditionalmnibus tests, and the new tests are constructed based on the componentsf Karhunen-Lo′eve expansion of limiting process. As examples, we constructests for the null hypothesis of stationarity, coefficient stability, symmetricynamics of quantile autoregressive model, and bivariate independence.imulation results show that, new tests have moderate size control and niceower performance for a wide range of alternatives. In contrast to traditionalmnibus tests, new tests are more robust to complex models and perform wellnder high-frequency alternatives. |
