My Master's project was about uncovering evolutionarily archetypal personality types from large amounts of personality data. Computationally, this involved rendering Big Five personality tests in a 5D space and running an archetypal analysis algorithm to find the extreme corner points that best enclosed the data in a simplex (a sort of 5-dimensional triangle with six corners).
At the time when I was doing the analysis, the best code for doing this
was based on
a 2012 paper
by Morten Mørup and Lars Kai Hansen, and written in Matlab. I'm not a
big fan of writing cross-language code so I ended up taking their
original Matlab code and translating the whole thing to Python. The
resulting package is called py_pcha and can be installed with
pip (pip install py_pcha).
