You don't see how possibly "a single well constructed model would control for weather, sociological and crime-factor variabes, and the intervention variable, ALL AT THE SAME TIME."? If you don't understand this, then what can I say. You have no background or knowledge of regression, ARIMA and modeling.

So you were not referring the specific data set, the weather data, the sociogical variables that the researchers used. So what you appear to have meant is that some of the data is public, but the actual complied dataset is not public. Is that correct? ------------------------ Yahoo!
