Try the book "Data Reduction and Error Analysis for the Physical Sciences" by Philip R Bevington. It was printed in 1969, and just this year, one of his colleagues updated the book. The 1992 version comes with a disk of the source code in Pascal. Both versions have the Fortran code. I just used the book to write a nonlinear least sqaures program using the Levenberg-Marquardt algorithm. Works great! Magdi N. Azer magdi@uxh.cso.uiuc.edu
