pca_weighting: 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)
Value
It returns a dataframe with rows = observations and column =
composite indicator
Arguments
data
dataframe with rows = observations and columns = quantitative
variables
