Transfer of Mathematical Formulas and Computer Algorithms into Macrocomparative Studies

In the article the mathematical formulas and computer algorithms: 1) mathematical formula of G. V. Rauschenbach; 2) electronic calculator of V. I. Levenstein; 3) formula of T. Sorensen were applied to the Nostratic data material of Nostratic etymon *wete "water", which is derivable through the etymons from five language families: Altaic, Afroasiatic, Dravidian, Indo-European, Uralic. It helped to establish the following degrees of Nostratic languages relationships: the close degree of relationship, which corresponds to the divergent-convergent development of Nostratic languages, is established between Altaic and Dravidian language families; remote degree of relationship, which corresponds to the convergent-divergent development, is established between the Dravidian and Uralic language families, while distant degree of relationship, which also corresponds to the convergent-divergent development, is established between Afroasiatic and Indo-European language families.
