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 Mestimators) and one diversity index and one inequality index. Moreover, functions for calculating the 1norm 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 phiwabl given a sample of trapezoidal fuzzy numbers.
