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.
