I once wondered, can we know based on a person's rating how many trips they've taken?
Not exactly the easiest question to answer, based on how it involves:
modeling, game theory, combinatorics, frequentist & bayesian statistics.
You see, ratings are based on 500 most recent trips.
The number of trips a person has taken is not visible.
5 ratings are possible: 1, 2, 3, 4, or 5 stars.
Ratings range from 1.00 to 5.00.
