Using concepts, identities, and/or equations discussed in class, demonstrate that the estimated coefficient of an explanatory variable in a multiple regression can be obtained in the following two steps:

1) Regress the explanatory variable of interest on all other explanatory variables

2) Regress the independent variable (y) on the residual obtained from step (1)

1) Regress the explanatory variable of interest on all other explanatory variables

2) Regress the independent variable (y) on the residual obtained from step (1)
