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.
