Abstract
ABSTRACTData envelopment analysis (DEA) assumes that data are continuous. However, there are situations where data are integers and bounded. For example, in basketball games, the total number of points that a player has scored is an integer and cannot exceed three times of the number of point field goals that a player has attempted. Without modelling the correct data type, the DEA results can be biased and erroneous. The current paper applies a bounded integer DEA model to evaluating the performance of National Basketball Association (NBA) players when bounded integer data exist. As a result, we correctly capture the data type. The current study also develops a super-efficiency measure under the bounded integer data. The bounded integer data problem is illustrated with data involving a set of NBA shooting guards in the 2013–2014 season.
