compindexR: An R package for calculating composite indicators

The package uses the first-order sensitivity index to measure whether the weights assigned by the creator of the composite indicator match the actual importance of the variables. Moreover, the variance inflation factor (VIF) is used to reduce the set of correlated variables.

In the case of a discrepancy between the importance and the assigned weight, the script determines weights that allow adjustment of the weights to the variables’ intended impact. If the optimised weights are unable to reflect the desired importance, the highly correlated variables are reduced, taking into account VIF.

The final outcome of the script is the calculated value of the composite indicator based on optimal weights and a reduced set of variables, and the linear ordering of the analysed objects.

Installing compindexR from CRAN

Please use following commands

install.packages("compindexR")
library(compindexR)

Installing compindexR - development version

Please make sure that you installed devtools package.

library(devtools)
install_github("olgnaydn/compindexR")

Example usage of the package.

Please make sure that you have readxl package installed. If its not installed, please install it using following commands

install.packages(readxl)
library(readxl)

From inst/extdata folder, import the excel file which is called cell_10.xlsx

x <- read_xlsx("cell_10.xlsx")

Run the following command to calculate composite indicator. Following command will allow you to choose average type as a arithmetic average, tolerance for Si calculation as 0.05, number of iterations to get Si as close to each other as possible, set VIF threshold.

calc_compindex(x, 
              avg_type = "simple", 
              scaling_method = "min-max", 
              vif_threshold = NULL, 
              si_diff = 0.005
              )

Command above will return a result as shown below
