I have no idea what you're talking about when you refer to "multiple models." I never said anything about multiple models. You seem to say the prediction based on past trends was unnecessary; but then to what do you compare the actual crime rate during the period to determine whether and how much it's been affected? Here's a report on the study that may provide some more detail, but there's not much about the specific statistical methodology: http://www.mum.edu/m_effect/dc_md.html ------------------------ Yahoo!
