The correlation coefficient is simply showing us that there is an exact match in unit change …
Webcorrelation function of X(t) and Y(t) is a function of time difference τ =t2 –t1only and not absolute time. i.e. RXY(t1,t2) = E[X(t1) Y(t2)] . If τ =t2 –t1 then RXY(t,t+ τ) = E[X(t) Y(t+ τ)] = RXY(τ). Therefore the conditions for a process to be joint wide sense stationary are 1. E[X(t)] = ̅ = constant. 2. E[Y(t)] = ̅ = constant 3.
