Regular point scoring by professional basketball players

In this paper we study the performance of basketball players paying special attention to stability and regularity with the focus on points scored. To this end we model regularity using the median absolute deviation for variables explaining its variation and we employed the Cochran variance outlier test to identify the players with largest variance in his performance. Also we analyze the ordinal patterns of player's performance considering short term evaluations (3 games per week). Our research provides an advancement on a simple but important question in basketball metrics: how to measure regularity in points scored and which factors may influence it.
