Download the latest version of ExaStat binaries for use on Win32 systems. This setup package installs a complete ExaStat binary tree and installs tools and project settings for Visual Studio 2005, Visual C++ Express 2005, and Visual Studio 2003, if you have any of those installed on your system. These binaries are compiled with Visual Studio 2005.

ExaStat now runs on Linux under Wine, which is available at http://www.winehq.com. See the Getting Started Using ExaStat document for more information about this.

We recommend using the free Visual C++ Express 2005 (available at http://msdn.microsoft.com/vstudio/express/visualc/) as the interface to ExaStat unless you just want to do simple interactive programming (the Census Demo uses only the interactive mode). Visual C++ Express 2005 provides a very good programming environment and an excellent compiler, ExaStat is tightly coupled to it, and it is hard to beat the price. Even if you only want to use the ExaStat interpreter, and do not intend to compile code, it has many advantages over other environments. (Of course, if you have a full version of Visual Studio 2005, that is preferred to the free version.)

If you are downloading ExaStat just to use the Census Demo, you do not need to install Visual Studio at this point. If you want to use it later, you can re-install ExaStat after you have installed Visual Studio so that ExaStat's setup program can install it's tools and addins.

Download the latest version of the ExaStat source tree for use on Win32 systems with Visual Studio 2005 and Visual C++ 2005 Express. This setup installs the entire ExaStat tree on your system along with batch scripts and Visual Studio solution files which allow you to build the complete tree.

You can use the free Visual C++ 2005 Express to build the source tree. However, you need to make sure you install the Platform SDK. This is the last part of the download procedure for Visual C++ 2005 Express (http://msdn.microsoft.com/vstudio/express/visualc/download/).

The objective of this demo is to show how it is possible to use ExaStat, along with R, to do exploratory data analysis on huge data sets. The data set used as an example is the 2000 U.S. Census 5% IPUMS sample.

ExaStat is used to process the data, to estimate models, and to put the results into a form suitable for graphing. R is used to display the results as Trellis plots.

The demo shows how to distribute the computations across computers, but the computations can easily be done on a single computer.

To get more of an idea of what the demo involves before downloading it, you can take a look at the Census Demo document by itself. This document is also included in the Census Demo setup, which you can download below.

Feedback of any type about the Census Demo and ExaStat is greatly appreciated, at censusdemo@exametrix.com.

In order to use the demo, you must do the following 4 things:

1. Install the ExaStat Win32 Binaries, which you can do above. You do not need to have Visual Studio or any other compiler on your system to go through the demo.

2. Install the Census Demo code and documentation, which you can do with the link below:

3. Install the latest version of R. You can do this at: http://www.r-project.org/

4. Install one or more of three possible Census data files. These are provided here as ZIP files, which you will need to upzip into the directory into which you install the Census Demo (the default is ExaStat\CensusDemo). The files when unzipped are ExaStat DataFiles.

File 1: CensusDemoData.zip. This is the recommended file. It contains all of the rows of the entire IPUMS file, but only contains those variables used in the demo. The download size is 90 MB, and the unzipped size is 630 MB.

File 2: CensusIp20001.zip. This contains the entire IPUMS file. The download size is 1 GB, and the unzipped size is 17 GB. You should download this if you are interested in exploring the Census beyond what is shown in the demo. Computation time for the demo is about the same whether you use the CensusDemoData file or this file, because ExaStat only reads the data it needs.

File 3: CensusWageExtract.zip. This file is about 63 MB zipped and about 386 MB unzipped. Use it as your primary file only if you do not have enough room on your computer for the CensusDemoData file. It contains a subselection of the rows but also adds some new variables. The equivalent of this file is created during the course of the demo. Much but not all of the demo can be done using just this file. If you download this file, you can skip the steps in the demo that create the file CensusWageExtract1.xdf.
