• C) If we plot the fitted or predicted values on the vertical axis versus the actual values \(\hat { y } _ {i}\)
• On the horizontal axis, and the plot yields points close to the \(60 ^ { \circ }\)
• Line, then the estimated regression function gives accurate predictions of the values actually observed.
