Robust Performance Hypothesis Testing with the Variance
Applied researchers often test for the difference of the variance of two investment strategies; in particular, when the investment strategies under consideration aim to implement the global minimum variance portfolio. A popular tool to this end is the F -test for the equality of variances. Unfortunately, this test is not valid when the returns are correlated, have tails heavier than the normal ...
متن کاملAsymptotically Minimax Robust Hypothesis Testing
The design of asymptotically minimax robust hypothesis testing is formalized for the Bayesian and Neyman-Pearson tests of Type I and II. The uncertainty classes based on the KL-divergence, αdivergence, symmetrized α-divergence, total variation distance, as well as the band model, moment classes and p-point classes are considered. It is shown with a counterexample that minimax robust tests do no...
متن کاملRobust Means Modeling: An Alternative for Hypothesis Testing of Independent Means Under Variance Heterogeneity and Nonnormality
This study proposes robust means modeling (RMM) approaches for hypothesis testing of mean differences for between-subjects designs in order to control the biasing effects of nonnormality and variance inequality. Drawing from structural equation modeling (SEM), the RMM approaches make no assumption of variance homogeneity and employ robust estimation/rescaling strategies in order to alleviate re...
متن کاملBayesian Fuzzy Hypothesis Testing with Imprecise Prior Distribution
This paper considers the testing of fuzzy hypotheses on the basis of a Bayesian approach. For this, using a notion of prior distribution with interval or fuzzy-valued parameters, we extend a concept of posterior probability of a fuzzy hypothesis. Some of its properties are also put into investigation. The feasibility and effectiveness of the proposed methods are also cla...
متن کاملRobust Hypothesis Testing via Lq-Likelihood
This article introduces a robust hypothesis testing procedure: the Lq-likelihoodratio-type test (LqRT). By deriving the asymptotic distribution of this test statistic, the authors demonstrate its robustness both analytically and numerically, and they investigate the properties of both its influence function and its breakdown point. A proposed method to select the tuning parameter q offers a goo...
