BLINWDR

BLINWDR: Robust and bounded influence regression. BLINWDR is a single FORTRAN program which represents an extension of the widely used linear robust curve fitting program LINWDR. Besides options for different loss functions in order to handle the problem of distributional robustness in regression, the program offers the choice between several weight functions which should bound the influence of outliers in the factor space. It combines these sophisticated methods with the user oriented features of LINWDR which are important in applied regression analysis.
