Urban sustainable development strategies are of great importance to rapidly urbanized countries such as China. One of the most challenging problems is how to coordinate urban spatial development with social efficiency and environmental protection, e.g., highly efficient low-carbon urban traffic. Despite broad research efforts with respect to the influence of urban form on travel patterns, quest...

Hypothesis testing is an important way to detect the statistical difference between two populations. In this paper, we use the Fisher permutation and bootstrap tests to differentiate hippocampal shape between genders. These methods are preferred to traditional hypothesis tests which impose assumptions on the distribution of the samples. An efficient algorithm is adopted to rapidly perform the e...

A study to reveal spatial distribution patterns in four characteristic dry forest tree species was undertaken in six one-hectare plots in the Cerros de Amotape National Park, northwestern Peru. The modified Ripley’s K statistic was used. Eriotheca ruizii (K. Schum.) A. Robyns (Bombacaceae), Bursera graveolens (Kunth) Triana & Planch. (Burseraceae), Caesalpinia glabrata Kunth (Leguminosae) and C...

BACKGROUND Several studies have investigated the implication of biological and environmental factors on geographic variations of end-stage renal disease (ESRD) incidence at large area scales, but none of them assessed the implication of neighbourhood characteristics (healthcare supply, socio-economic level and urbanization degree) on spatial repartition of ESRD. We evaluated the spatial implica...

In the past few years, several new tests for spatial clustering have been proposed. With ever increasing capability of GIS and wider availability of spatial statistic functions, spatial analysts are likely to face challenge of properly using these tests. Seemingly gaps also exist between the development of new tests and follow up evaluations against various assumptions. In this research note, I...

OBJECTIVES To measure the spatial contagion of severe acute respiratory syndrome (SARS) in Beijing and to test the different epidemic factors of the spread of SARS in different periods. METHODS A join-count spatial statistic study was conducted and the given hypothetical processes of the spread of SARS in Beijing were tested using various definitions of 'joins'. RESULTS The spatial statisti...

Event Detection Identifying patterns of interest in large temporal datasets Spatial Scan Statistic A method for identifying hotspots in spatial data, widely used in epidemiology and biosurveillance Scoring Function An objective function that measures the anomalousness of a subset of data LTSS Linear-time subset scanning Time to Detect Evaluation metric; time delay before detecting an event Over...

The spatial distribution pattern of cultural resource generally manifests clustered qualification to some extent, and we can infer the vicissitudes of the correlative culture by analyzing the changing rule of the spatial distribution pattern of cultural resource. However, the majority of the concerned researches are still at the level of qualitative statistics and thematic map visualization of ...
