Code for paper "The evolution of paradigms from Latin to Romance"

This is the code used to obtain the results shown in the paper "The evolution of paradigms from Latin to Romance. A quantitative approach". The jupyter notebook "Romance entropy.ipynb" takes as input paradigmatic lexicons (in the folder data/lexicons) and entropy results obtained via the Qumin toolkit (in the folder results/qumin) to obtain the tables and figures of Sections 4.1 and 4.2. In the folder "frequency_analysis", there are the R code and necessary input data to obtain the results shown in Section 4.3 on the role of frequency.
