pca_weighting {Indicator}

Function that weight the quantitative variable by PCA method

Description

The pca_weighting function is designed to perform a principal component analysis (PCA) on the input data to calculate weights that correct for overlapping information between related indicators. This process makes it possible to create a composite indicator that captures as much information as possible from individual indicators while reducing the dimensionality of the data

Usage

pca_weighting(data)

Arguments

data

dataframe with rows = observations and columns = quantitative variables

Value

It returns a dataframe with rows = observations and column = composite indicator
