summary.dea: Summary conventional DEA models.

Description

Summary of the results obtained by a conventional DEA model.

Usage

# S3 method for dea
summary(object, exportExcel = FALSE, filename = NULL, returnList = FALSE, ...)

Value

Depending on the model it returns a single data.frame containing: efficiencies, slacks, lambdas, targets, references or a list of data.frames with the cross-efficiencies computed with different methods (Arbitrary, Method II or Method III (see CITA)) or, in case the model is a Malmquist index, a single data.frame with the coefficients for the different periods.

Arguments

object

An object of class "dea" obtained by a DEA model function.

exportExcel

Logical value. If TRUE (FALSE by default) the results are also exported to an Excel file.

filename

Character string. Absolute file name (including path) of the exported Excel file. If NULL, then the file name will be "ResultsDEA" + timestamp.xlsx.

returnList

Logical value. If TRUE then the results are given as a list of data frames. If FALSE (default) all the data frames are merged into a single data frame.

...

Ignored. Used for compatibility issues.
