Recent advances in the implementation of spatial econometrics model estimation techniques have made it desirable to compare results, which should correspond between implementations across software applications for the same data. These model estimation techniques are associated with methods for estimating impacts (emanating effects), which are also presented(More)
Developing spatial econometrics functions in R can not only enable analysts to advance our own techniques using convenient interpreted language features. Placing spatial econometrics and more generally spatial statistics in the context of an extensible data analysis environment also exposes similarities and differences between traditions of analysis. These(More)
is a language similar to for statistical data analysis, based on modern programming concepts and released under the GNU General Public License. It permits the integration of program scripts with compiled dynamically loaded libraries of functions when computing speed is important. Following a broad outline of existing collections of functions for spatial(More)
Much of the analysis of regional growth in Europe in recent years has concentrated on the concept of convergence, whether in the neo-classical model, or in alternative formulations. Empirical work has shifted from more confirmatory non-spatial estimation to the acknowledgement of the importance of spatial factors, including spillovers, and to exploratory(More)
Schistosomiasis control in China has, in general, been very successful during the past several decades. However, the rebounding of the epidemic situation in some areas in recent years raises concerns about a sustainable control strategy of which locating active transmission sites (ATS) is a necessary first step. This study presents a systematic approach for(More)
Schistosomiasis control in China is facing a new challenge due to the rebound of epidemics in many areas and the unsustainable effects of the chemotherapy-based control strategy. Identifying high-risk regions for schistosomiasis is an important first step for an effective and sustainable strategy. Direct surveillance of snail habitats to detect high-risk(More)
