: 3 For Square Integrable Random Variables X Y E L And A B E R We Define Yab A Bx Assume That O X 0 And O Y 0 For 1 (23.85 KiB) Viewed 35 times

3. For square-integrable random variables X,Y E L² and a, b E R we define Yab=a+bX. Assume that o(X) >0 and o(Y) > 0 for the variances of X and Y. Show that inf E(Y-Yab)² = E(Y-Yab)² = 0² (Y). (1-p²(X,Y)), a,bER where a* = E(Y)-b* E(X), b* = Cov(X,Y) 0²(X)
