FuzzyStatTra: Statistical Methods for Trapezoidal Fuzzy Numbers
The aim of the package is to provide some basic functions
for doing statistics with trapezoidal fuzzy numbers. In particular,
the package contains several functions for simulating trapezoidal
fuzzy numbers, as well as for calculating some central tendency
measures (mean and two types of median), some scale measures
(variance, ADD, MDD, Sn, Qn, Tn and some M-estimators) and
one diversity index and one inequality index. Moreover,
functions for calculating the 1-norm distance, the mid/spr
distance and the (phi,theta)-wabl/ldev/rdev distance between
fuzzy numbers are included, and a function to calculate the
value phi-wabl given a sample of trapezoidal fuzzy numbers.
