The true positive rate is the number of the predicted positives out of true positives and the true negative rate is the number of the predicted negatives out of the number of false positives.

 

Upon regressing blood pressure on age, obtaining the residuals, and plotting the residuals against the predictor weight, we obtain the following "residuals versus weight" plot: This "residuals versus weight" plot can be used to determine whether we should add the predictor weight to the model that already contains the predictor age.

 

Once we've explained the variation in the individuals' blood pressures by taking into account the individuals' ages and weights, no significant amount of the remaining variability can be explained by the individuals' durations.

 

If this is not clear enough, perhaps others on this forum might be able to clarify it.
