A Bi-Robust Test for Vague Data

Przemys law Grzegorzewski.

Nonparametric statistical tests are
robust to disturbances of the assumptions
on the underlying distributions.
However, in the presence
of vague data, modelled by fuzzy
sets, the problem of robustness is
much more complicated. Here not
only distribution-free methods but
tests which are also not sensitive to
the particular choice of the membership
functions applied for modelling
vague concepts would be desirable.
A construction of such bi-robust test
is suggested in the paper.
