10. The Shapley Value
The Shapley value is a way to assign credit among a group of “players” who cooperate for a certain end
An example:
• 3 players
(2 with right glove and 1 with left glove)
• Goal: Form a pair
• Assign credit to each player after forming a pair
There are two possible pairs that we can form and in both of them, Player 1 needs to be involved. Therefore, Player 1, is of more importance compared to Player 2 or
Player 3. Consequently, when sharing the profits, he should get a bigger part compared to Player 2 (if we case 1 is true) or Player 3 (if case 2 is true)

19. Survival Analysis
Estimate time-to-event for a group of
individuals, such as time until a visitor purchases
To compare time-to-event between two or
more groups, such as visitors that have clicked
on a Display ad compared to visitors that have
not clicked on a Display ad.
To assess the relationship of co-variables to
time-to-event, such as: does number of clicks,
pages viewed, or time on site effect the decision
to purchase?
