A recurring problem at the U. S. Naval Civil Engineering Laboratory NCEL concerns the fitting of experimental data to an empirical or semiempirical formula of nonlinear form. Such problems, which involve asymptotic growth curves, are not amenable to solution by the usual linear least squares curve fitting techniques. Since nonlinear curve fitting problems have arisen in connection with various NCEL tasks, it appeared desirable to devise and adapt general mathematical methods for treating a class of nonlinear problems. This report describes methods for performing nonlinear curve fits, together with a method for choosing the best of several possible empirical formulas. FORTRAN computer programs are provided, and applications to NCEL tasks are discussed. Author
