Abstract
Over the years data analytics for sports has developed consistently. Survival analysis is a method that allows to study the occurrence of a particular event during a period of follow-up. This work aims studying the main achievements associated to the probability of reaching a certain amount of points during a NBA season segment. A Stepwise Cox regression model and a Lasso Cox regression were used to select the most important variables. Two settings were examined, with 20% and 50% censoring. Results showed that attempting more shots, gaining more achievements (double doubles) and having been selected for the All-Star game increase the probability of success, i.e. exceeding the given threshold of points. Moreover, a higher number of steals seems to decrease the probability of reaching a certain amount of points. Thus, players more involved in this fundamental are penalized in terms of scored points.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
