New point and interval estimators for quantiles that employ a control variate are introduced. The properties of these estimators do not depend on the usual assumption of joint normality between the random variable of interest and the control. Illustrative examples for queueing and stochastic...

small as two, their power is reasonably close to the power envelopes for similar and non-similar tests which are invariant …-sided conditional t-tests found in Andrews et al. (2007). We show these tests have bad power because the conditional null distributions …

Inferences based on spatial analysis of areal data depend greatly on the method used to quantify the degree of proximity between spatial units - regions. These proximity measures are normally organized in the form of weights matrices, which are used to obtain statistics that take into account...

This article describes how modeling positional uncertainty helps to understand potential factors of uncertainty, and to identify impacts of uncertainty on spatial analysis results. However, modeling geocoding positional uncertainty still is limited in providing a comprehensive explanation about...

Zusammenfassung Querschnittsdaten aus benachbarten Raumgebieten, wie in der Regionalökonomie verwendet, weisen neben Heteroskedastie oft auch gegenseitige Abhängigkeiten auf. Aufgrund des geringen Bekanntheitsgrades der Raumstrukturellen Ökonometrie wird es häufig versäumt, die...

Gridded land surface temperature data products are used in climatology on the assumption that contaminating effects from urbanization, land-use change and related socioeconomic processes have been identified and filtered out, leaving behind a “pure” record of climatic change. But several...
