Weighted on-base average (wOBA) for hitters from the 2022 Major League Baseball (MLB) season. Standard errors are calculated by modeling hitting outcomes as multinomially distributed and plugging in empirical proportions as the “true” outcome probabilities. To handle small sample sizes, standard errors are lower bounded by the errors that would be obtained using league-wide proportions rather than the plug-in estimates.
wOBA is a data frame with 688 rows and 6 columns:
The hitter's FanGraphs identifier.
The hitter's name.
The hitter's MLB team (given as a three-letter code) or
NA if the hitter played for multiple teams.
The hitter's number of plate appearances over the 2022 season.
The hitter's wOBA over the 2022 season.
The standard error for the hitter's wOBA.
