My stylometric analysis gave us a sharp division between stories written by professional authors and stories from fimfiction. A very big part of that was using Equestrian vocabulary.
stylo produces a file, 'wordlist.txt', that lists all the words to be used for the analysis. You can take that file, add or remove words, and then check the box Features -> Existing wordlist to use that file instead of generating a new one.
I removed Equestrian vocabulary from wordslist:
I haven't read Go Set a Watchman, the new old book by Harper Lee, who wrote To Kill a Mockingbird. But Stylo has.
I think Eleanor Roosevelt had baboon arms. I mean I can't totally confirm this and maybe it was just the dress she was wearing but it looked like she had some King Louis length arms going on there. It was almost as if she could scratch the back of her knee without having to reach. Again I can't confirm this but it was just something I noticed before she started reading something from General Washington (obviously this was before he became president).
