报告内容摘要:
This article proposes new nonparametric tests to check the adequacy of the conditional mean specification for multiplicative error models (MEM) satisfying Markov structures. Our tests are based on a novel projection device, which kills "parameter estimation uncertainty" and also motivates a convenient multiplier bootstrap procedure to simulate critical values of the proposed tests as accurately as desirable. In addition, our tests are fully data-driven, do not require kernel function or user-chosen tuning parameters such as bandwidths, and are able to detect a broad class of local alternatives converging to the null at the parametric rate $n^{-1/2}$, with $n$ the sample size.
