  In this paper, we develop a novel depth-based testing procedure on spatial
point processes to examine the difference in made and missed field goal
attempts for NBA players. Specifically, our testing procedure can statistically
detect the differences between made and missed field goal attempts for NBA
players. We first obtain the depths of two processes under the polar coordinate
system. A two-dimensional Kolmogorov-Smirnov test is then performed to test the
difference between the depths of the two processes. Throughout extensive
simulation studies, we show our testing procedure with good frequentist
properties under both null hypothesis and alternative hypothesis. A comparison
against the competing methods shows that our proposed procedure has better
testing reliability and testing power. Application to the shot chart data of
191 NBA players in the 2017-2018 regular season offers interesting insights
about these players' made and missed shot patterns.
