I have data counting the number of words that appear in text reviews, each review rated 1 to 5 stars. So for every word, I have the rating breakdown of reviews that contain that word.
I would like to perform a beta-binomial analysis on each word by rating (n=4) but I also want the rating categories to be evenly weighted (currently 5-star reviews are 59% of total reviews). If I proportionally weight the numbers (e.g. multiply by total number of reviews and divide by total number of reviews with that star rating), can I still say meaningful things about the data?
