Impact of climate change and development scenarios on flow patterns in the Okavango River [PDF]
This paper lays the foundation for the use of scenario modelling as a tool for integrated water resource management in the Okavango River basin. The Pitman hydrological model is used to assess the impact of various development and climate change ...

$H_0$-Contiguity in Nonparametric Testing Problems and Sample Pitman Efficiency
The concept of $H_0$-contiguity is studied for certain nonparametric testing problems. Furthermore, it is shown that a meaningful sample definition of Pitman efficiency is possible under $H_0$-contiguity, and this definition turns out to coincide with the usual efficiency concept based on comparing asymptotic distributions.

A Condition Under Which the Pitman and Bahadur Approaches to Efficiency Coincide
The approximate Bahadur efficiency and the Pitman efficiency for hypothesis testing problems are considered. A theorem is stated and proved which gives a condition under which the existence of the limiting (as the alternative approaches the hypothesis) approximate Bahadur efficiency implies the existence of the limiting (as the significance level ...

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

On the limiting Pitman asymptotic relative efficiency of two Cramér-von Mises tests
The Cramér-von Mises test is one of the classical goodness-of-fit tests, for simple as well as for composite null hypotheses. In the classical theory of independent and identically distributed data the corresponding test statistic is based on the empirical distribution function, which is well known to be the nonparametric maximum likelihood estimator ...

On the limiting Pitman efficiency of some rank tests of independence
Kendall's tau and Spearman's rho may be expressed by the use of standard sequences with parameter \(a=1\). The paper uses the fact that the main assumption of \textit{H. S. Wieand}'s theorem [Ann. Stat. 4, 1003-1011 (1976; Zbl 0351.62033)] may be replaced by an equivalent one which is presented in section 2.

The impact of predation by marine mammals on Patagonian toothfish longline fisheries [PDF]
Predatory interaction of marine mammals with longline fisheries is observed globally, leading to partial or complete loss of the catch and in some parts of the world to considerable financial loss.
