Meet the human data

Welcome to the Dimensionality reduction techniques chapter.

In this chapter we will be using the human dataset to introduce Principal Components Analysis (PCA). The data originates from the United Nations Development Programme. See their data page for more information. For a nice overview see also the calculating the human development indices pdf.

Most of the variable names have been shortened and two new variables have been computed. See the meta file for the modified data here for descriptions.
