Hi, i am looking to gain some insight into a relationship between two variables. The equation i am interested in is z = average xy / (average x . average y) where x and y are time series. Ideally i would like to show this relationship on some form of distribution. Any insight would be appreciated. Thanks TrBo

This is a question of correlation. If there is no correlation between x and y, z = 1.
