The aim of the package is to provide some basic functions for doing
statistics with one dimensional Fuzzy Data (in the form of polygonal fuzzy
numbers). In particular, the package contains functions for the basic
operations on the class of fuzzy numbers (sum, scalar product, mean,
Hukuhara difference) as well as for calculating (Bertoluzza) distance,
sample variance, sample covariance, sample correlation, and the
Dempster-Shafer (levelwise) histogram. Moreover a function to simulate
fuzzy random variables, bootstrap tests for the equality of means, and a
function to do linear regression given trapezoidal fuzzy data is
included.
