This paper proposes a new class of characteristic-function-based distribution tests for two-sample comparison, simple hypotheses, and conditional distribution assumptions of econometric models. The proposed tests are easy to compute and have χ2(2) as the asymptotic null distribution. Comparing to the Kolmogorov-Smirnov (KS) and Cramérvon Mises (CV) tests, the proposed test can flexibly account ...
