WebThe linear regression equation for predicting systolic blood pressure from age is as follows: y = 54 +3.6x. Find the residual for a person who is 25 years of age with a systolic blood pressure of 148. Hint: Make sure you are subtracting in the correct direction. WebFor simple linear regression, the least squares estimates of the model parameters β 0 and β 1 are denoted b0 and b1. Using these estimates, an estimated regression equation is constructed: ŷ = b0 + b1x . The graph of the estimated regression equation for simple linear regression is a straight line approximation to the relationship between y and x.
