5. Consider the fitted values that result from performing linear regres- sion without an intercept. In this setting, the ith fitted value takes the form yi = xiB, where B (3.38) Show that we can write n yi = > aryi' . i' =1 What is a;? Note: We interpret this result by saying that the fitted values from linear regression are linear combinations of the response values
