Kobe’s FGP – Time Series of Spatial Processes



Spread across time, each colored line is a hexagonal area of the court. Based on intuition, you can guess that the areas where Kobe’s Field Goal Percentage (FGP) is higher are the ones closer to the rim and/or his favorite sweet spots. Most of them hover around 40 percent. Around 2006, Kobe’s Court X Time FGP are pretty stable.

However, 2007 and beyond, Kobe’s Court X Time FGP show more fluctuations. Pau Gasol anyone? He’ll be missed by LA.

Space-time data sets and analysis techniques are becoming more a-la-mode. First, you must choose a way to think about the joint ‘space-time’ structure (think electro-magnetism).

One simple way is to consider space and then time; resulting in a time series of spatial processes. This is like a stack of papers, each piece of paper is a slice of time across space. Alternatively, you can consider time and then space where the analogue would be a bundle of straws, each straw being a time series. The brave-hearted might pursue ‘non-seperable’ techniques and look at space-time together.

In the near future, i’ll present what we can do with these ideas and this space-time dataset of Kobe’s FGP.
