Regression Line. The simple linear regression equation is graphed as a straight line where. In statistics linear regression is a linear approach to modelling the relationship between a scalar response and one or more explanatory variables also known as dependent and independent variables the case of one explanatory variable is called simple linear regression.
The sum of the residuals is zero if the model includes an intercept term. In statistics linear regression is a linear approach to modelling the relationship between a scalar response and one or more explanatory variables also known as dependent and independent variables the case of one explanatory variable is called simple linear regression. The line of best fit is described by the equation ŷ bx a where b is the slope of the line and a is the intercept i e the value of y when x 0.

Regression lines are very useful for forecasting procedures. The sum of the residuals is zero if the model includes an intercept term. I 1 n ε i 0. So our y intercept is going to be 1.
