The Multiple Testing Issue in Geographically Weighted Regression   总被引:3,自引:0,他引:3       下载免费PDF全文
This article describes the problem of multiple testing within a Geographically Weighted Regression framework and presents a possible solution to the problem which is based on a family‐wise error rate for dependent processes. We compare the solution presented here to other solutions such as the Bonferroni correction and the Byrne, Charlton, and Fotheringham proposal which is based on the Benjamini and Hochberg False Discovery Rate. We conclude that our proposed correction is superior to others and that generally some correction in the conventional t‐test is necessary to avoid false positives in GWR.  相似文献

Constitutional designers often construct political institutions to provide greater autonomy to ethnic minority groups. One tool available to constitutional designers is ‘ethnic gerrymandering’, where the boundaries of local government units are altered to provide greater representation to minority groups. This paper analyses the effects of changes in the ethnic composition of municipalities, which occur as a result of ethnic gerrymandering, on ethnic party behaviour. I compare ethnic party behaviour in local elections in the Republic of Macedonia from 2000 to 2013. I expand on a theory initially proposed by Sherrill Stroschein linking ethnic demography to ethnic party behaviour. I find that changes in the ethnic composition of municipalities influence whether rival ethnic parties engage in outbidding or whether ethnic communities unite behind a single ethnic party. My findings have important implications for those tasked with designing political institutions in ethnically divided societies.  相似文献

In the third book of Otia Imperialia (c. 1211), Gervase of Tilbury describes numerous wonders, among them an English belief regarding the Grant, a sparkling-eyed entity shaped like a bipedal foal, whose appearance racing through the streets forewarns of fire. This creature, attested to nowhere but in Gervase’s work, is something of a mystery for folklorists, who have tried to draw connections to other supernatural beings based on its name and its appearance. What has gone overlooked is the fact that the same elements of the Grant’s fire-omen belief existed well into the twentieth century in parts of England, albeit applied to hares. This article suggests that the Grant is an exaggerated hare, while exploring the larger topic of why it is that hares are so often associated with fire in European folklore.  相似文献

The long‐held redistributive function of agricultural cooperatives — one of moral economy and poverty alleviation — has changed dramatically as they emerge as core brokers for agro‐industrial development in the so‐called ‘green economy’. This article examines the changing role of cooperatives involved in brokering oil palm production and its impact upon the food security and livelihoods of smallholders who labour in plantation regimes situated in historically uneven agrarian political economies. Findings show how, increasingly, cooperatives reinforce uneven agrarian social relations of production and exchange in which indigenous smallholders experience loss of land, poor wage labour conditions tinged with insecurity and prejudice, and mounting debt in an expanding oil palm complex. The article suggests that these changes in agrarian social relations negatively influence indigenous farmers’ food security pathways, with their access to and use of appropriate foods diminishing. It asserts that understanding the impacts of cooperatives on food security pathways requires a relational and situated analysis of livelihood change and agrarian relations in extractive frontiers.  相似文献
