Standard error of estimate regression formula
WebbIn simple linear regression, the starting point is the estimated regression equation: ŷ = b 0 + b 1 x. It provides a mathematical relationship between the dependent variable (y) and the independent variable (x). Furthermore, it can be used to … WebbError = Actual Value− Predicted Value Error = Actual Value − Predicted Value For the simple linear regression model, the standard error of the estimate measures the average vertical distance (the error) between the points on the scatter diagram and the regression line.
