- Suppose that the random change in value of a financial asset is X over the first day and Y over the second. Suppose also that Var(X) =18 and Var(Y) = 26 In this case, the total change in the value over these two days is given by X +Y. Do you have enough information to compute Var(X +Y)? If so, compute this value. If not, explain what additional information you need to do so.Y, = XB + ɛ, Show that the model variance in model Yi unbiased estimator ofQ5 Find the variance for the PDF px(x) = e-«/2, x > 0.
