%description
Estimators for fuzzy linear regression. The functions estimate parameters
of fuzzy linear regression models with crisp or fuzzy independent
variables (triangular fuzzy numbers are supported). Implements multiple
methods for parameter estimation and algebraic operations with triangular
fuzzy numbers. Includes functions for summarising, printing and plotting
the model fit. Calculates predictions from the model and total error of
fit. Individual methods are described in Diamond (1988)
