ABSTRACT

Numerous experimental studies involve semi-quantitative expert information,
or measured in a non-precise way, which can be modeled with interval
(fluctuations, grouped data, etc.) or fuzzy (ratings, opinions, perceptions
etc.) data. A general framework to analyze these kinds of inexact data with
statistical tools developed for Hilbertian random variables will be
presented. Robust estimation in Hilbert spaces is specially relevant for
its applications in the treatment of contaminated functional data.
Specifically, the trimmed mean was already defined and analyzed under ideal
conditions. However its estimation has not been efficiently implemented. An
algorithm to compute the sample trimmed mean in Hilbert spaces is presented
and its robust properties are briefly discussed. To show the performance of
the algorithm some case studies concerning functional and fuzzy data will
be presented.
