I am within the stochastic course of course and there’s a half that I do not perceive:
Let $$X_0, X_1, X_2, X_3 sim N(0;1), |a| < 1$$
So $$ cov(a^3X_0+a^2X_1+aX_2+X_3;a^2X_0+aX_1+X_2)=a^5+a^3+a $$
Might anybody can clarify for me why we’ve that covariance end result as above?
Thanks in your assist!
