NettetThe regression equation is an algebraic representation of the regression line. The regression equation for the linear model takes the following form: Y= b 0 + b 1 x 1. In the regression equation, Y is the response variable, b 0 is the constant or intercept, b 1 is the estimated coefficient for the linear term (also known as the slope of the ... NettetFitting the Multiple Linear Regression Model. Recall that the method of least squares is used to find the best-fitting line for the observed data. The estimated least squares regression equation has the minimum sum of squared errors, or deviations, between the fitted line and the observations. When we have more than one predictor, this same ...
