WebFeb 19, 2024 · A player with an intra-game goals/game rate that follows Poisson distribution is completely expected. A player who is streaky will likely deviate from this distribution. In other words a streaky player will have more 0 goal games, less 1 goal games, and more multiple goal games than predicted by the Poisson distribution. WebWhat is a Bootstrap? Bootstrap is a method of inference about a population using sample data. Bradley Efron first introduced it in this paper in 1979. Bootstrap relies on sampling with replacement from sample data.
