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

Reliability Class Testing Hypothesis for EBUCL^*t₀ With Applications for Medical and Engineering Data Modeling

IEEE Access
This paper introduces a new reliability class, the exponential better than used after age $t_{0}$ in increasing convex Laplace transform order ( $EBUCL^{\ast }t_{0}$ ), and develops a corresponding statistical test for exponentiality.

On a New NBRUL*t₀ Reliability Class and Efficient Tests of Exponentiality: Mathematical Theory and Applications

Mathematics
In this paper, we introduce a new age-dependent reliability class, termed the new better (worse) than renewal used in Laplace transform order after age t0 (NBRUL∗t0).

On the Pitman Efficiency of One-sided Kolmogorov and Smirnov Tests for Normal Alternatives

The Annals of Mathematical Statistics, 1966
1. Summary. Lower bounds for the Pitman efficiency of the one-sided Kolmogorov test for all normal alternatives and for the Smirnov test for normal shift alternatives are obtained. In the one-sample case this does not fall below 36 per cent at the usual levels of significance and power. In the two-sample case the lower bound depends on the ratio of the

Pitman Efficiencies of Sequential Tests and Uniform Limit Theorems in Nonparametric Statistics

The Annals of Statistics, 1978
In this paper Pitman's method of constructing and comparing tests based on statistics which are asymptotically normal under the null hypothesis and the local alternatives is extended to sequential tests of statistical hypotheses. The asymptotic normality assumption in Pitman's theory is replaced in its sequential analogue by the weak convergence of ...

A simple and efficient method for sampling mixture models based on Dirichlet and Pitman-Yor processes

Computational Statistics
Abstract We introduce a simple and efficient sampling strategy for the Dirichlet process mixture model (DPM) and its two-parameter extension, the Poisson-Dirichlet process mixture model, also known as the Pitman-Yor process mixture model (PYM).

On the limiting Pitman asymptotic relative efficiency of two Cramér-von Mises tests

, 2013
Einer der klassischen Anpassungstests der Statistik ist der Cramér-von Mises Test, sowohl für eine einfache als auch für eine zusammengesetzte Hypothese. Im Fall von unabhängig und identisch verteilten Beobachtungen beruht die zugehörige Teststatistik dabei auf der klassischen empirischen Verteilungsfunktion, welche bekanntermaßen der ...
