Supplementary material for "Mutual predictiveness of sound correspondences for reconstruction and language subgrouping: The case of Gyalrongic preinitials"

This is the supplementary material of the paper "Mutual predictiveness of sound correspondences for reconstruction and language subgrouping: The case of Gyalrongic preinitials", to be published in Diachronica. It includes the datasets, codes and images involved in the research. Publication is still several months away, and I am trying to collect and identify more cognates as well as correct mistakes. 

Version 2 has included a few more cognates. I have added a file explaning my cognate judgements and annotations, and removed some doubtful forms after verification with native speakers.
