Extract information from a dea class object and compute some more.
# S3 method for dea
summary(object, ...)This function returns the following information, as a named list:
Model name: if it is previously set
Orientation: Model orientation
Inputs: Names of the input variables in the model
Outputs: Names of the output variables in the model
nInputs: Number of the input variables in the model
nOutputs: Number of the output variables in the model
nVariables: Total number of input and output variables in the model
n: Number of DMUs
nEfficients: Number of efficient DMUs taking into account whithin eff.tolerance tolerance.
Mean: Mean of efficiency scores.
sd: Standard deviation of efficiency scores.
Min.: Minimun value of efficiency scores.
1st Qu.: First quater of efficiency scores.
Median: Median of efficiency scores.
3rd Qu.: Third quater of efficiency scores.
Max.: Maximum value of efficiency scores.
is the object of class dea to summarise
For compatibility reason, see note about `eff.tolerance` parameter.
The default tolerance to consider a DMU as efficient one is .001 in reports. Use `eff.tolerance` parameter to consider another tolerance between 0 and 1.
