NettetIn the regression equation y= b0 + b1x + b2dx with a dummy variable d, when d changes from 0 to 1, the change in the slope of the corresponding lines is given by: A. b0 B. b0 +b1 C. b2 D. b0 + b2 C. b2 In the model y = β0 + β1x + β2d + β3xd + ε, when d changes from 0 to 1 how does the intercept of the corresponding lines change? NettetLinear regression finds the optimal linear relationship between independent variables and dependent variables, thus makes prediction accordingly. The simplest form is y = b0 + b1x. When there is only one input feature, linear regression model fits the line in a 2 dimensional space, in order to minimize the residuals between predicted values and ...
