Depth-Based Signed-Rank Tests for Bivariate Central Symmetry
Revstat Statistical Journal, 2020 In this paper, distribution-free, affine invariant, signed-rank test statistics are proposed for the hypothesis that a bivariate distribution is centrally symmetric about an arbitrary specified point.

Suspend tests and rankings [PDF]
Science, 2020 The notion that U.S. colleges and universities will open this fall in “normal” mode should not be in any forecast. As Dr. Anthony Fauci (of the White House's coronavirus task force) testified last week before the Senate, it's unlikely that a vaccine or treatments for coronavirus disease 2019 (COVID-19) will be available by the time students return to ...

Econometric Theory, 2000 This paper considers tests for the rank of a matrix for which a root-T consistent estimator is available. However, in contrast to tests associated with the minimum chi-square and asymptotic least squares principles, the estimator's asymptotic variance matrix is not required to be either full or of known rank.

Pseudo-Gaussian and Rank-Based Tests for First-Order Superdiagonal Bilinear Models in Panel Data
Revstat Statistical Journal, 2021 In this paper, locally asymptotically optimal (in the H´ajek-Le Cam sense) parametric, pseudo-Gaussian and rank-based procedures are proposed for the problem of testing randomness against first-order superdiagonal bilinear panel dependence (in large n ...

Comparing Survival Curves Using Rank Tests [PDF]
, 1990 Survival times of patients can be compared using rank tests in various experimental setups, including the two-sample case and the case of paired data. Attention is focussed on two frequently occurring complications in medical applications: censoring and ...

Nonparametric Rank Tests for Independence in Opinion Surveys
Austrian Journal of Statistics, 2016 Nonparametric rank tests for independence between two characteristics are commonly used in many social opinion surveys. When both characteristics are ordinal in nature, tests based on rank correlations such as those due to Spearman and Kendall are often ...

A note on the power of panel conitegration tests - An application to health care expenditure and GDP [PDF]
, 2016 This paper enlarges on Gutierrez's (2003) results on the power of panel cointegration tests. By a comparison of power of panel cointegration tests, we show how the choice of most powerful test depends on the values ...
