Like the Committee of Operations Analysts the Policy Tensor has been perfecting the technique of data analysis and visualization. The problem that I identified when I decomposed the variation explained into components due to each predictor was that fixed-effects are signed. By squaring the coefficients we lose the information contained in the signs of the coefficients. When we compare multiple models of the world, the natural empirical strategy is to embed them in an enveloping model that contains the alternate models as particular cases (given by linear restrictions). In order to distinguish the wheat from the chaff we have to get a handle on how much work each variable is doing. That can tell us an awful lot about what's going on.
