A Nonparametric Test of the Leverage Hypothesis [PDF]
The so-called leverage hypothesis is that negative shocks to prices/returns aect volatility more than equal positive shocks. Whether this is attributable to changing nancial leverage is still subject to dispute but the terminology is in wide use. There are many tests of the leverage hypothesis using discrete time data.

The purpose of this article was to introduce the likelihood ratio test, six nonparametric tests, and the SAS implementation of the survival data. Based on the assumption that the survival data had the exponential distribution, the likelihood ratio test ...

Nonparametric Hypothesis Tests for Statistical Dependency [PDF]
Determining the structure of dependencies among a set of variables is a common task in many signal and image processing applications, including multitarget tracking and computer vision. In this paper, we present an information-theoretic, machine learning approach to problems of this type. We cast this problem as a hypothesis test between factorizations

An Entropy-Based Approach for Nonparametrically Testing Simple Probability Distribution Hypotheses
In this paper, we introduce a flexible and widely applicable nonparametric entropy-based testing procedure that can be used to assess the validity of simple hypotheses about a specific parametric population distribution. The testing methodology relies on

On the Power of Some Nonparametric Isotropy Tests
In this paper, properties of nonparametric significance tests verifying the random field isotropy hypothesis are discussed. In particular, the subject of the conducted analysis is the probability of rejecting the null hypothesis when it is true.

Sign, Wilcoxon and Mann-Whitney Tests for Functional Data: An Approach Based on Random Projections
Sign, Wilcoxon and Mann-Whitney tests are nonparametric methods in one or two-sample problems. The nonparametric methods are alternatives used for testing hypothesis when the standard methods based on the Gaussianity assumption are not suitable to be ...

NonpModelCheck: An R Package for Nonparametric Lack-of-Fit Testing and Variable Selection
We describe the R package NonpModelCheck for hypothesis testing and variable selection in nonparametric regression. This package implements functions to perform hypothesis testing for the significance of a predictor or a group of predictors in a fully ...

Application of the empirical Bayes approach to nonparametric testing for high-dimensional data
In [5] a simple, data-driven and computationally efficient procedure of (nonparametric) testing for high-dimensional data have been introduced. The procedure is based on randomization and resampling, a special sequential data partition procedure, and χ2 ...

Universal Codes as a Basis for Time Series Testing [PDF]
We suggest a new approach to hypothesis testing for ergodic and stationary processes. In contrast to standard methods, the suggested approach gives a possibility to make tests, based on any lossless data compression method even if the distribution law of
