Median values (and interquartile ranges, in brackets) of inputs and outputs divided in two groups: efficient and non-efficient units in each model.
Table 5.
Mean efficiency scores in each model, mean SMR and SRU, number of units in each category, and number of units considered efficient in each model.
The best results in each category and column are in bold.
Fig 1.
Scatter plot showing all units’ SMR and SRU.
The blue color represents the units considered efficient, and the size is proportional to the number of times the unit was considered a reference to others. The dashed lines are the median values of SMR (horizontal) and SRU (vertical).
