Question: Confirm the partialling out interpretation of the OLS estimates by explicitly doing the partialling out for Example 3.2. This first requires regressing educ on exper and tenure and saving the residuals, \(\hat{r}_{1} .\) Then, regress \(\log (\) wage ) on \(\hat{r}_{1} .\) Compare the coefficient on \(\hat{r}_{1}\) with the coefficient on educ in the regression of log(wage) on educ, exper, and tenure.
