sir we have already taken A such that (Z,X_2) are independent then why we have to check cov(Z,X_2)=0 because in previous lectures we find A using COV. property and also just on the basis of E(X_1|X_2) and V(X_1|X_2) how can we say that it follow multivariate normal distribution
THANKS 😊 SO MUCH SIR
