Abstract:
|
In baseball, heat maps, which visualize a batter's ability across regions in and around the strike zone play an important role in baseball commentary and scouting reports. We simulate the stochastic process underlying these heat maps as a spatial Gaussian field with isotropic covariance. Spatial interpolation (kriging) relies on the covariance parameters assumed to be known, but in reality they are estimated from the same data. Our simulation study helps to understand and explain the spatial dependence of the process, thus allowing us to produce heat maps that more accurately represent batters' true ability.
