SpaceStat—空间计量模型软件软件介绍，SPACE模型。

软件简介

SpaceStat它涵盖了在空间技术统计和空间计量经济学的合理范围。提供了spaciotemporal和统计工具，包括广泛的套房：探索性空间数据分析;空间计量分析，以及空间的权重集和变差函数模型的创建。SpaceStat提供广泛的时空(spatiotemporal )和统计工具，包括:探索性空间数据分析(exploratory spatial dataanalysis);空间计量分析(spatial econometric analyses)和空间权重集和变异函数模型的建立(the creation of spatial weights sets and variogram models)。单独使用SpaceStat或配合Esri的ArcGIS一起使用可以大幅扩展您的GIS分析功能。

软件特点

SpaceStat有以下几大特点：

回归工具

SpaceStat的aspatial回归工具(aspatial regression tools)，包括线性，泊松(Poisson)和logistic回归，允许您在一个软件包包进行从时空数据探索(spatio-temporaldata exploration)到模型构建的操作。除了回归工具的这些"简单"形式，SpaceStat还允许你使用模型构建工具，如最佳子集，向前和向后逐步回归。所有这些工具都可以应用到数据集，包括多次(multiple times)，它允许你快速评估模型的拟合和其他参数如何随时间而改变。

改善的差异统计(DisparityStatistics)

SpaceStat让您在四种不同的方式为您的数据：从一个点或多边形的地理聚集改变空间的支持不同的点或多边形地理，或从点到多边形，反之亦然。

导入Microsoft Office Excel文件数据

为了简化导入数据的过程，我们现在提供了直接从Microsoft Office Excel导入数据的选项。您可以使用此选项引入一个新的point geography，或添加数据集到到您SpaceStat项目中的现有的地域(geographies )。

复制图形，地图和表格到剪切板

地图/图形菜单现在包括一个选项,复制一个给定的图形或地图映射到剪贴板，以便您可以将其粘贴到文字处理或演示文件中（例如，Microsoft PowerPoint），可以在不同的软件程序中打开。您可以使用Edit菜单上的复制选项来对表格执行类似的功能，直接复制表格到Microsoft Excel表格中。

英文概述

SpaceStat Overview

StaceStatallows you to view the data in your project, display these data in maps andgraphs, and to perform statistics to evaluate spatial patterns. What makes thissoftware unique is that it is a space-time information system. In StaceStat,time is a dimension of the data, rather than an attribute linked to each objectin the dataset.  Thus, almost all viewsof the data can be animated, from maps to histograms to tables. But,StaceStat  does more than just animateyour data, it allows you to make statistical inferences about patterns in thedata as well. StaceStat allows you to view, interact with and statisticallyanalyze your space-time data so that you can make informed decisions.

Overthe past year, we have added powerful new tools for manipulating data andperforming statistical analyses, including several which are not available inany other software package.  In addition,we have improved data import by adding the option to import geographies orattribute data directly from Microsoft Office Excel files, and made it easy tocopy graphs or maps from SpaceStat and paste them into other programs.  Here we provide an overview of the featureswe have availble in SpaceStat.

Regression tools

Althoughcertainly not unique to SpaceStat, aspatial regression tools, including linear,Poisson, and logistic regression allow you to go from spatio-temporal dataexploration to model building within one software package.  In addition to the "simple" formsof these regression tools, SpaceStat also allows you to use model buildingtools such as best subset, and forward and backward stepwise regression.  All of these tools can be applied to datasetsthat encompass multiple times, which allows you to quickly evaluate how modelfit and other parameters change over time.

InSpaceStat, you can also perform geographically-weighted regression (local, ratherthan global regression analyses); as with aspatial regression, your GWR modelscan have a linear, Poisson, or logistic form.

UsingSpaceStat, you can not only build both spatial and aspatial models, you can runmodels developed using one method (i.e., as an aspatial linear model) inanother form (i.e., aspatial Poisson, or linear GWR), and use our wealth ofdata exploration tools to explore how this change in tools influences theresults of your analysis over all of the time periods in your datasets.

Improved Disparity Statistics

Followingthe publication of advances in quantifying health disparities by Goovaerts etal. (2007), we are the first to make these advances available in a softwarepackage.

New ways to AggregateData/Change your Spatial Data Support

SpaceStatallows you to aggregate (change the spatial support) for your data in fourdifferent ways:  from a point or polygongeography to a different point or polygon geography, or from points to polygonsand vice versa.

Import data as MicrosoftOffice Excel files

Tosimplify the process of importing data, we now provide the option of importingdata directly from Microsoft Office Excel. You can use this option to bring in a new point geography, or to adddatasets to existing geographies in your SpaceStat project.

Copy Graphs, Maps, and Tablesto the Clipboard

TheMap/Graph menus now include an option to copy an image of a given graph or mapto the clipboard so that you can paste the image into word processing orpresentation (e.g., Microsoft Powerpoint) files open in different softwareprograms.  You can perform a similarfunction with the copy option in the Edit menu for tables, and copy tabularinformation directly into Microsoft Excel.
