基于我找到的这个网址 Bayesian Rating

avg_num_votes  = Sum(votes)/Count(votes) * Count(votes)

avg_rating     = sum(votes)/count(votes)

this_num_votes = count(votes)

this_rating    = Positive_votes - Negative_votes

它看起来更像这样:

avg_num_votes  = Count(votes)/Count(items with at least 1 vote)
avg_rating     = Sum(votes)/Count(items with at least 1 vote)

this_num_votes = Count(votes for this item)
this_rating    = Sum(votes for this item)/Count(votes for this item)

Sum(votes) = Count(positive votes) (即将+视为1,-视为0)
