Dear all,
Please could you help me with the following.
I am trying to solve a problem in which it is asked to compute Covariance(X,Y).
The information the problem gives are:
sum Xi = 859; sum Xi^2 = 47 387 sum Yi = 1 095; sum Yi^2 = 78 737 sum XiYi = 60 262; n = 18; i = 1, ...n
COV(X,Y) = ?
Many thanks!
