摘要:	Consider an ordinary errors-in-variables model. The true level an(θ) of a test at nominal level a and sample size n is called to be pointwise robust if an (θ)→ α as n → ∞ for each parameter θ. Define an = sUPθEnan(θ), where n is the parameter space of θ. The test is said to be uniformly robust over Ω if an → α as n → ∞. It is known that all existing large-sample tests for the key parameters are pointwise robust but not uniformly robust, even for a narrow subset of parameter space. In this talk, we construct uniformly robust tests for some primary parameters in both functional and structural errors-in-variables models. These results can be used to establish the related confidence sets with certain desirable property in the same models. A small simulation showing that the proposed tests are superior to the ordi!1ary large-sample ones in the finite sample is also provided.
