Model Fitting: Linear Regression

The Linear Regression analysis fits a linear regression model by using ordinary least squares. You can write the multiple linear regression equation for a model with explanatory variables as

where

is the response variable, the

's are explanatory variables, and the

's are regression coefficients.

You can run a Linear Regression analysis by selecting Analysis $\blacktriangleright\,$ Model Fitting $\blacktriangleright\,$ Linear Regression from the main menu. The computation of the regression function, confidence limits, and related statistics is implemented by calling the REG procedure in SAS/STAT. See the documentation for the REG procedure in the SAS/STAT User's Guide for additional details.
