How to Analyze the Regression Analysis Output from Excel In a simple regression model‚ we are trying to determine if a variable Y is linearly dependent on variable X. That is‚ whenever X changes‚ Y also changes linearly. A linear relationship is a straight line relationship. In the form of an equation‚ this relationship can be expressed as Y = α + βX + e In this equation‚ Y is the dependent variable‚ and X is the independent variable. α is the intercept of the regression line‚ and β is the
