make_malmquist function

make_malmquist

This function creates, from a data frame, a list of deadata objects.

make_malmquist(datadea,
               nper = NULL,
               percol = NULL,
               arrangement  = c("horizontal", "vertical"),
               ...)

Arguments

• datadea: Data frame with DEA data.
• nper: Number of time periods (with dataset in wide format).
• percol: Column of time period (with dataset in long format).
• arrangement: Horizontal with data in wide format. Vertical with data in long format.
• ...: Other options to be passed to the make_deadata function.

Returns

An object of class deadata

Examples

# Example 1. If you have a dataset in wide format.
data("Economy")
data_example <- make_malmquist(datadea = Economy, 
                               nper = 5, 
                               arrangement = "horizontal",
                               ni = 2, 
                               no = 1)
# This is the same as:
data_example <- make_malmquist(datadea = Economy,
                               nper = 5, 
                               arrangement = "horizontal",
                               inputs = 2:3, 
                               outputs = 4)
# Example 2. If you have a dataset in long format.
data("EconomyLong")
data_example2 <- make_malmquist(EconomyLong,
                                percol = 2, 
                                arrangement = "vertical",
                                inputs = 3:4, 
                                outputs = 5)
