This paper reviews important concepts and methods that are useful for hypothesis testing.First, we discuss the Neyman-Pearson framework. Various approaches to optimalityare presented, including finite-sample and large-sample optimality. Then, some of the mostimportant methods are summarized, as...

Consider the problem of testing s hypotheses simultaneously. In order to deal with themultiplicity problem, the classical approach is to restrict attention to procedures that controlthe familywise error rate (FWE). Typically, it is known how to construct tests of the individualhypotheses, and...

Consider the problem of testing s hypotheses simultaneously. In this paper, we derivemethods which control the generalized familywise error rate given by the probability ofk or more false rejections, abbreviated k-FWER. We derive both single-step and stepdownprocedures that control the k-FWER in...

International evidence on the accrual anomaly is sparse and conflicting. Testing for accrual mispricing in 28 equity markets, we provide statistical evidence for anomalous returns in some countries. However, we question whether this result might have occurred by chance alone and that it might...

We propose a simple class of semiparametric multivariate GARCH models, allowing for asymmetric volatilities and time-varying conditional correlations. Estimates for time-varying conditional correlations are constructed by means of a convex combination of estimates for averaged correlations...

This paper uses a new approach to determine the fraction of truly skilled managers among the universe of U.S. domestic-equity mutual funds over the 1975 to 2006 period. We develop a simple technique that properly accounts for “false discoveries,” or mutual funds which exhibit significant...

In this paper we analyze the distribution of fertility rates across theworld using parametric mixture models. We demonstrate the existence of twinpeaks and the division of the world's countries in two distinct components: ahigh-fertility regime and a low fertility regime. Whereas the signicance...

Applied researchers often test for the difference of the variance of two investment strategies;in particular, when the investment strategies under consideration aim to implementthe global minimum variance portfolio. A popular tool to this end is the F-test for theequality of variances....

This Monte-Carlo study investigates sensitivity of the Wilcoxon signed rank test to certainassumption violations in small samples. Emphasis is put on within-sample-dependence,between-sample dependence, and the presence of ties. Our results show that both assumptionviolations induce severe size...

We find that price and earnings momentum are pervasive features of international equitymarkets when controlling for data snooping biases. For European countries, we find that pricemomentum is subsumed by earnings momentum on an aggregate level. However, this rationaledoes not apply to each and...
