Question
Suppose the regression specification y(hat) = a + βx
+ l z + ε was estimated as y = 5 + 6x + 7z. We have a new observation for which x = 5 and z = -2. For this new observation the associated value of true y isSolution
ŷ is related to sample. We can only estimate ŷ and cannot calculate its true value.
