We randomize the excluded variables to keep sample from being biased, trying to achieve as minimal an error as possible 2. Results The results are an estimate Idea is to keep it as small as possible The overall goal is to minimize estimation error The results are probabilistic not deterministic Independent variables Do the independent variables cause the behavior?
