  "Description": "Estimates the standard and weighted Elo (WElo, Angelini et\nal., 2022 <doi:10.1016/j.ejor.2021.04.011>) rates. The current\nversion provides Elo and WElo rates for tennis, according to\ndifferent systems of weights (games or sets) and scale factors\n(constant, proportional to the number of matches, with more\nweight on Grand Slam matches or matches played on a specific\nsurface). Moreover, the package gives the possibility of\nestimating the (bootstrap) standard errors for the rates.\nFinally, the package includes betting functions that\nautomatically select the matches on which place a bet.",
