educ.jmu.eduNotes prepared by Pamela Peterson Drake 5 Correlation and Regression Simple regression 1. Regression is the analysis of the relation between one variable and some other variable(s), assuming a linear relation. Also referred to as least squares regression and ordinary least squares (OLS). A. YThe purpose is to explain the variation in a variable (that is, how a …

Ordinary least squares Example 1: Basic linear regression Suppose that we have data on the mileage rating and weight of 74 automobiles. The variables in our data are mpg, weight, and foreign.

First, when the number of predictors is large, it is computationally infeasible to do subset selection.
