I am trying to correlate revenue with some economic factors (i.e. employment, house price index and CPI) however I can only find a correlation for the last 3 years and during the recession period, my correlations are all over the place. My concern is that this might mean that there is probably no correlation in reality and I am just benefitting from the upward trend...
Has anyone else witnessed the same and can anyone shed some light on this?
Not sure what you're talking about. According to several recent news articles the average american income is no better off than it was in 1999.
What revenue are you talking about? Tax revenue, business revenue? It could be that your model is too simplistic and your signal is being overwhelmed by noise. How are you generating your correlations?
