Efficient plot-based floristic assessment of tropical forests [PDF]
, 2003 The tropical flora remains chronically understudied and the lack of floristic understanding hampers ecological research and its application for large-scale conservation planning.

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.

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 ...

Landscape Review, 2017 The increase in urban population has required cities to rethink their strategies for minimising greenhouse gas impacts and adapting to climate change. While urban design and planning policy have been guided by principles such as walkability (to reduce ...

Pitman Efficiency Lower Bounds for Multivariate Distribution-Free Tests Based on Optimal Transport
, 2021 Distribution-free tests such as the Wilcoxon rank sum test are popular for testing the equality of two univariate distributions. Among the important reasons for their popularity are the striking results of Hodges-Lehmann (1956) and Chernoff-Savage (1958), where the authors show that the asymptotic (Pitman) relative efficiency of Wilcoxon's test with ...

Estimating rainfall and water balance over the Okavango River Basin for hydrological applications [PDF]
, 2006 A historical database for use in rainfall-runoff modeling of the Okavango River Basin in Southwest Africa is presented. The work has relevance for similar data-sparse regions.

Testing equality of variances in the analysis of repeated measurements [PDF]
, 1993 The problem of comparing the precisions of two instruments using repeated measurements can be cast as an extension of the Pitman-Morgan problem of testing equality of variances of a bivariate normal distribution.

Service provider difficulties in operationalising coercive control [PDF]
, 2019 We examined perspectives of social workers, police officers, and specialist domestic abuse practitioners about their perceived ability and organizational readiness to respond effectively to incidents of coercive and controlling behavior.

Efficient vs. structured biodiversity inventories: reptiles in a Mexican dry scrubland as a case study [PDF]
Animal Biodiversity and Conservation, 2018 Many sampling methods allow the study of species richness and diversity in biological communities, but it is not known whether a single method can determine both the number and diversity of species in an unbiased and efficient way. Here we assess whether

Pitman Efficiencies of Kolmogorov-Smirnov Tests
The Annals of Mathematical Statistics, 1971 A comparison, by means of Pitman asymptotic efficiency, is made between the Kolmogorov-Smirnov test and the locally most powerful rank and the locally asymptotically most powerful (Neyman) test for testing two-sided shifts in the two-sample problem under the assumption that the true distribution is different from the one assumed.
