Query: The Advantage of Playing Home in NBA: Microscopic, Team-Specific and
  Evolving Features   The idea that the success rate of a team increases when playing home is
broadly accepted and documented for a wide variety of sports. Investigations on
the so-called home advantage phenomenon date back to the 70's and every since
has attracted the attention of scholars and sport enthusiasts. These studies
have been mainly focused on identifying the phenomenon and trying to correlate
it with external factors such as crowd noise and referee bias. Much less is
known about the effects of home advantage in the microscopic dynamics of the
game (within the game) or possible team-specific and evolving features of this
phenomenon. Here we present a detailed study of these previous features in the
National Basketball Association (NBA). By analyzing play-by-play events of more
than sixteen thousand games that span thirteen NBA seasons, we have found that
home advantage affects the microscopic dynamics of the game by increasing the
scoring rates and decreasing the time intervals between scores of teams playing
home. We verified that these two features are different among the NBA teams,
for instance, the scoring rate of the Cleveland Cavaliers team is increased
0.16 points per minute (on average the seasons 2004-05 to 2013-14) when playing
home, whereas for the New Jersey Nets (now the Brooklyn Nets) this rate
increases in only 0.04 points per minute. We further observed that these
microscopic features have evolved over time in a non-trivial manner when
analyzing the results team-by-team. However, after averaging over all teams
some regularities emerge; in particular, we noticed that the average
differences in the scoring rates and in the characteristic times (related to
the time intervals between scores) have slightly decreased over time,
suggesting a weakening of the phenomenon.
