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) 該電影評價 v = number of votes for the movie = (votes) 該電影投票數 m = minimum votes required to be listed in the Top 250 (currently 25000) 要進入top 250最少投票數 (目前 25000) C = the mean vote across the whole report (currently 7.0) 所有入榜電影評價的平均值? (目前 7.0)
For the Top 250, only votes from regular voters are considered.
