TAASSC 2 (Python)

[A Zakaria]

Hi, 

I wanted to clarify how the indices in the TAASSC 2.XX (Python) code are calculated. 

I understand for indices like noun phrase complexity indices, they are calculated by number of variable divided by the number of np_structure (in the code, using safe_divide). (I may be mistaken on this, please correct me if I am). 

I might have missed something but I cannot figure out how indices like pronouns (pp1, pp2 and pp3) are calculated. 

Is it total number of variable divided by total number of tokens? If you could point me to the lines in the code, that could also help. 

Thank you. 

Regards,
