Methods are provided for fitting a curve to a set of data values using a lea st absolute value (LAV) cost function. The set of data values may comprise m sets of dat a values. The method takes advantage of contraction mapping to determine a number n &l t; m of individual equations which are interpolated by the curve to be fitted, where n corresponds to the number of parameters x1 , x2 ,..., x n to be ascertained for the curv e to be fitted. The method then involves solving the n selected equations to determine the n parameters x1, x2,..., x n of the curve to be fitted. Selection of these parameters ensures that the curve to be fitted minimizes the LAV cost function.
