Nate Silver correctly called 50 out of 50 states
Nate Silver's calculations are certainly more sophisticated that a simple time-weighted average of legitimate polling numbers, but are they more accurate?<p>His baseball projection system, PECOTA, was <i>extremely</i> complex, but barely, <i>barely</i> outperformed a simple 3-year weighted average with an age component (Marcel), and some years was worse. Other projection systems that didn't take player comps into account were better overall than PECOTA (CHONE being the best, before the creator was hired away by a team).
