Positive spatial dependence is predominant in the spatial data. Therefore, it is not surprising that most of the methodological papers are concerned with the positive spatial dependence (either in terms of spatial lag, spatial error, or both) when evaluating estimation, testing and forecasting procedures [For example, see Anselin, Bera, Florax, and Yoon (1996) and Baltagi, Song, and Koh (2003) ...
Much progress has been made in the development of software tools for spatial analysis since special issue Geographical Analysis appeared 2006, devoted to “Recent advances social sciences” (Rey and Anselin 2006). The 15 some years publication have marked by major changes analytical landscape. Arguably, three important somewhat related phenomena can be distinguished that drove these changes: embe...

The numerical analysis of spatial point distributions has interested academics for many years. A very early work that resulted in the famous Moran’s I statistic was that by Moran (1948). An early important collection of work on general spatial analysis is that edited by Berry and Marble (1968). The development of spatial point analysis theory is illustrated by such later books by Cliff and Ord ...

این تحقیق با هدف تعیین غلظت، تعیین منشأ احتمالی، نقشه سازی توزیع مکانی، تعیین نقاط hotspot و ارزیابی خطر ptes (عناصر بالقوه سمی)، در خاک های سطحی منطقه اراک به وسعت 600 کیلومترمربع با استفاده از فناوری gis، ژئواستاتیستیک و تحلیل چندمتغیره انجام گرفت. در مجموع 190 نمونه خاک مرکب (عمق 0-20 سانتی متر) با استفاده از سیستم نمونه برداری سیستماتیک تصادفی جمع آوری شدند. بدین ترتیب تعداد 62 نمونه خاک سط...
Dense Acropora cervicornis aggregations, or patches, have been documented within nearshore habitats in Southeast Florida (SE FL) despite close proximity to numerous anthropogenic stressors and subjection to frequent natural disturbance events. Limited information has been published concerning the distribution and abundance of A. cervicornis outside of these known dense patches. The first goal o...
