On the combination of the sign and Maesono tests for simmetry and its efficiency
Statistica, 2007 We propose a new test for the simmetry hypothesis which is a combination of the sign statistic and the Wr Maesono statistic. The latter generalizes the Wilcoxon statistic and coincides with it for r = 2. The proposed statistic belongs to the class of non-

On Hodges and Lehmann's "$6/\pi$ result" [PDF]
, 2013 While the asymptotic relative efficiency (ARE) of Wilcoxon rank-based tests for location and regression with respect to their parametric Student competitors can be arbitrarily large, Hodges and Lehmann (1961) have shown that the ARE of the same Wilcoxon ...

Performance Analysis of Gini Correlator for Detecting Known Signals in Impulsive Noise
IEEE Access, 2019 Detection of known signals embedded in additive noise is a fundamental problem in signal processing. For normally distributed noise, it is well known that the popular matched filter detector (MFD) is optimal.

Wild dogs at stake: deforestation threatens the only Amazon endemic canid, the short-eared dog (Atelocynus microtis) [PDF]
, 2020 The persistent high deforestation rate and fragmentation of the Amazon forests are the main threats to their biodiversity. To anticipate and mitigate these threats, it is important to understand and predict how species respond to the rapidly changing ...

A Note on Detecting “More IFR-ness” Property of Life Distributions [PDF]
, 2012 In this paper, a problem of testing whether one life distribution possesses “more IFR” property than the other is considered.A new test procedure is proposed and the distribution of the test statistic is studied.
