Baseball sabermetric functions, in python/sagemath (sagemath.org)
This file is intended to mine data from Retrosheet event files.
To create the log file for a report of the form (for example) "Game states via Retrosheet: Errors in DET 2019 home games" perform the following steps:
- add subdirectory "DET-home_2019" to events
- run sage: frequency_transitions_team_season(season = 2019, team="DET", post_season = False, save_game_files = True) sage: Errors_DET_2019 = errors_in_homegames(season = 2019, team = "DET", verbose=True)
- Save screen output to "errors-in-DET-2019-homegames_sage-log.txt"
- edit to a latex file.
