ci_rbod_dir: Directional Robust Benefit of the Doubt approach (D-RBoD)

Description

Directional Robust Benefit of the Doubt approach (D-RBoD) is the directional robust version of the BoD method.

Usage

ci_rbod_dir(x,indic_col,M,B,dir)

Value

An object of class "CI". This is a list containing the following elements:

ci_rbod_dir_est

Composite indicator estimated values.

ci_method

Method used; for this function ci_method="rbod_dir".

Arguments

x

A data.frame containing score of the simple indicators.

indic_col

Simple indicators column number.

M

The number of elements in each of the bootstrapped samples.

B

The number of bootstap replicates.

dir

Main direction. For example you can set the average rates of substitution.
