A general class of means introduced by Italian mathematician Oscar Chisini (pronounced keeseenee) in 1929.
Given a function of variables
, the Chisini mean of
values
associated with
is defined as the number
such that
![]() |
Of course, the function must be chosen in such a way that there always is exactly one number
with this property.
The most common means are Chisini means associated with the functions listed in the following table. Every weighted mean corresponds to the weight vector .
