WebFOCUS RStat is a data mining and predictive modeling workbench embedded in WebFOCUS Developer Studio. RStat supports common statistical and data mining tasks and the development of predictive models that can be deployed as scoring applications on any WebFOCUS platform. RStat enables data miners and Business Intelligence developers to collaborate with the same tools to access, manipulate, and transform data, develop predictive models, and incorporate this scoring functionality into operational Business Intelligence applications. Data models include decision trees, neural networks, linear and logistic regressions, random forests, support vector machine, boosting, association rules, K-means, and hierarchical clustering.

The latest release of RStat 1.3.1 includes the following:

• Model Export C files compliant for Teradata UDF (User Defined Function) for in-database processing.
  • The new Teradata UDF export function in RStat generates a C program that is Teradata UDF compliant for in-database processing. When scoring large amounts of data, running the predictive model using in-database processing results in significant performance gains.
  • After selecting Teradata UDF as an export option, a C file and a CREATE FUNCTION template are created for the purpose of creating the Teradata UDF, in a directory of your choice. Using the template and following the UDF creation process, the UDF is created in Teradata that is equivalent to the RStat deployed model in WebFOCUS. The defined function in Teradata can then be used from native Teradata clients, BI, and ETL.
• Ability to load R scripts to the RStat GUI.
  • The Rscript button in RStat GUI can load an R script with all models that R supports. If a new package is required, the new package is loaded accordingly for specific model and code executions. Files or plots are outputted in the R console or a new window, and then saved to the directory that is specified in the R script.
  • For models that are already implemented in RStat, C routines can be exported. These models include Regression, Decision Trees, Clusters, Survival Model, and Market Basket.
