SAN DIEGO--(BUSINESS WIRE)--Nov. 5, 2002

Stone Analytics(R), a leading provider of embeddable analytic software and an ESRI(R) Business Partner, today announced the availability of Valuation Science(TM) as a fully integrated extension of ESRI's popular GIS and mapping software ArcView(R).

Valuation Science, which is also compatible with the ArcView business product Business Analyst, is an analytic engine that can be embedded in enterprise applications that process and store information about sales, marketing, and customer activity.

Valuation Science generates statistical models that identify the underlying patterns in company information. Business managers can use Valuation Science to understand and forecast purchase behavior, measure customer value, and better allocate sales, marketing, and customer-relationship resources.

"We are very excited about releasing a second product integrated with ESRI's ArcView," said Stone Analytics CEO Christy Joiner-Congleton. "Valuation Science provides additional functionality to ESRI's ArcView users and strengthens the relationship between the companies. Combining Valuation Science's analytic capabilities with Business Analyst's EBIS demographic and business data, and ArcView's geographic display allows business managers to gain additional insight into their information, and then display their findings in an understandable manner. This synergy of technologies and data has many applications. It would be particularly useful when doing site location, because users could clearly identify where to place their next store so as to maximize expected revenue and profit."

Valuation Science employs some of the most robust and effective modeling techniques available, including Stone Analytics' proprietary Automatic Analyst(TM) technology, which enables users to carry out advanced statistical analysis without any prior training. Automatic Analyst automates the modeling process, including data exploration and preprocessing, which typically takes 60 to 80% of an analyst's time during a modeling project. Automatic Analyst also handles problematic data, such as missing records and outliers, and automatically partitions the data set into random test and train subsets to protect against sample bias. Automatic Analyst offers the benefits of predictive modeling without requiring a statistician.

Valuation Science can be obtained through Stone Analytics Authorized Resellers, a list of which can be found by visiting Stone Analytics at www.stoneanalytics.com.
