Question regarding index of CRAT tool

[Andrew Jaeho Shin]

Hi Professor,

I'm using CRAT tool to analyze some texts and came up with a question regarding index.

In your index spreadsheet, there are

proper_n_perc: percentage of text consisting of proper nouns, 

and

pronoun_perc: percentage of text consisting of proper nouns. Do they represent the same thing? Or the latter is actually pronouns?

Also, I was wondering if indices such as nwords, nparagraphs, nsentences, function_perc, and pronoun_perc are measured based on a given text regardless of source text?

Thank you so much for the tool.

Best,

Andrew
