I think you need to provide much more information in order for people to help interpret them. Such as did you create these? What doe the coefficient variable represent? What do you mean over time, people clusters across time, but how was this structured in the model?
Thanks for the reply. Yes, I created these. So I want to measure the relationship between a profitabilty index (Malmquist Index, measures the relative productivity increase compared to the previous period) and the change of the UEFA-club coefficient (again over the previous period) for football clubs. I have panel data over multiple seasons.
