摘要：
In this article a new approach for checking the adequacy of GARCH-type models in time series was proposed. The resulted tests involve weight functions, which provide them with the flexibility in choosing scores to enhance power performance. The choice of weight functions and the power properties of the tests are studied. For a large number of alternatives, asymptotically distribution-free maximin test; is constructed. The tests are asymptotically chi-squared under the mill hypothesis and easy to implement. Simulation results indicate that the tests perform well.
