Product Description

e2gStats Demo is a free demonstration version of the e2gStats Basic app (see http://expertise2go.com/e2gstats/). It provides a sample of e2gStats Basic's integrated collection of data analysis methods supporting course work and research activity in the social sciences, including business and education. The app and its documentation emphasize statistical analysis of data gathered through questionnaires.

A variety of data analysis methods, grouped into five analysis objectives are supported. These five analysis objectives include Descriptive Statistics, Hypothesis Testing, Correlation and Regression, Analysis of Variance, and Nonparametric Statistics.

e2gStats Demo includes a data editor that presents the data in a grid format similar to a spreadsheet. The editor supports entry of small data sets and modification of data files created by the editors or imported from other software. The data format is comma separated values (CSV), so spreadsheets and database managers that export .csv files may also be used for data preparation. Input data may be created with a text editor. These externally prepared data files may be downloaded from the Internet or e-mailed to the Android device.

Two sample data files are automatically installed with the app. These files support the mini-course scenarios and allow immediate experimentation with the software.

e2gDroid Lite is an Android port of the e2gRuleEngine Java applet: a rule-based expert system "shell" used in Decision Support and Expert System courses around the world for more than 10 years. e2gDroid delivers mobile, interactive decision making tools in the form of rule-based expert systems on Android devices that implement at least the version 1.6 "Donut" OS.

An e2gDroid rule-based expert system application is delivered by the expert system shell and defined by a knowledge base: a text script that provides the decision logic in the form of "if-then" rules, the user interface in the form of "prompt" definitions for interacting with the expert system and control parameters. The user of an expert system application will be asked a series of questions driven by the decision logic to provide data that allows the expert system shell’s inference engine to make its recommendations.

The expertise2go.com Web site provides a series of tutorials that introduce expert system concepts and design techniques. Access to a variety of example knowledge bases is provided from the e2gDroid Lite menu and on the Web site. It is intended that knowledge bases be developed and tested first with the e2gRuleEngine applet because of its diagnostic support, then delivered for e2gDroid Lite use from the developer's Web site.

Features:

* Rule-based expert system shell with backward-chaining inference engine
* Explanation mechanism explains "why" questions asked and "how" conclusions reached
* Certainty/confidence factor processing supported
* Restarting consultation at earlier prompt supported
* Knowledge bases optionally link to Web pages for help ("Infolinks") or to support conclusions ("Hyperlinks")
* Android device memory/SD card storage of knowledge bases after Internet download
* Translate mechanism facilitates internationalizing knowledge bases
* Extensive Web site support for expert system developer training
