Building a Linear Regression Model

Topics:

WebFOCUS RStat is a statistical modeling workbench embedded in Developer Studio that enables data exploration, hypothesis testing, data mining, and model development for scoring applications. RStat enables data miners and Business Intelligence developers to work collaboratively with the same tools to access, manipulate, or transform data, develop predictive models, and create and deploy scoring applications, along with associated reports, to any worker within their organization.

The WebFOCUS RStat tool logically proceeds by progressing through the tabs: first load the data, select variables for exploring and mining, possibly sample the data, explore the data, build your models, and evaluate them.

The Regression, Decision Tree, and Cluster models are the most commonly used models for predictive analytics.

This chapter explains how regression works with one dependent and one independent variable (simple regression), and how regression works with multiple independent variables (multiple regression).
