11.47 Predicting bone formation. Let’s use regression methods to predict VO+, the measure of bone formation.

a. Because OC is a biomarker of bone formation, we start with a simple linear regression, using OC as the explanatory variable. Run the regression and summarize the results. Be sure to include an analysis of the residuals.

b. Because the processes of bone formation and bone resorption are highly related, it is possible that there is some information in the bone resorption variables that can tell us something about bone formation. Use a model with both OC and TRAP, the biomarker of bone resorption, to predict VO+ . Summarize the results. In the context of this model, it appears that TRAP is a better predictor of bone formation, VO+ , than the biomarker of bone formation, OC. Is this view consistent with the pattern of relationships that you described in the previous exercise? One possible explanation is that, although all these variables are highly related, TRAP is measured with more precision than OC.
