Predicting One Depression Score from Another Example 1.28 and Exercise 2.209 introduce a study examining the impact of diet on depression. The study used two different ways to measure depression: the DASS, which uses self-reported symptoms, and the CESD, a more clinical assessment. On both scales, higher numbers indicate greater depression symptoms. Figure below shows the regression line on the scatterplot of the depression scores for each of the 75 participants at the start of the diet/depression experiment (before the effect of any dietary intervention.)

For the one with a self-reported score of 0, estimate: the clinical score, the predicted clinical score, and the residual. Clinical score = i Predicted clinical score = i Residual = i
