%description
Principal Component Analysis (PCA) is a statistical technique used to
reduce the dimensionality of a dataset while preserving as much
variability as possible. By transforming the original variables into a new
set of uncorrelated variables called principal components, PCA helps in
identifying patterns and simplifying the complexity of high-dimensional
data. The 'RankPCA' package provides a streamlined workflow for performing
PCA on datasets containing both categorical and continuous variables. It
facilitates data preprocessing, encoding of categorical variables, and
computes PCA to determine the optimal number of principal components based
on a specified variance threshold. The package also computes composite
indices for ranking observations, which can be useful for various
analytical purposes. Garai, S., & Paul, R. K. (2023)
