Empirical Determination of Baseball Eras: Multivariate Changepoint Analysis in Major League Baseball
We use multivariate change point analysis methods, to identify not only mean shifts but also changes in variance across a wide array of statistical time series. Our primary objective is to empirically discern distinct eras in the evolution of basebal
