Does anyone have an example formula that can be used to sort by a 5 star rating
in SOLR?
I am looking at an example on IMDB's top 250 movie list:
The formula for calculating the Top Rated 250 Titles gives a true Bayesian
estimate:
weighted rating (WR) = (v ÷ (v+m)) × R + (m ÷ (v+m)) × C
where:
R = average for the movie (mean) = (Rating)
v = number of votes for the movie = (votes)
m = minimum votes required to be listed in the Top 250 (currently 3000)
C = the mean vote across the whole report (currently 6.9)
