Notes:
a
Results from estimating equation (2).
b
Avg(Ability) is the average handicap of a player’s playing partners, as described in the text.
c
Column (1) includes the average of all of the other players in your tournament-by-category urn (not including yourself). This control is necessary to produce a well-behaved randomization test (see text for more details).
d
Standard errors are in parentheses and are clustered by playing group.
e
All regressions are unweighted (unlike the specifications in the other tables), since the weighting is not appropriate for the randomization test.
