NLLS: A 704 PROGRAM FOR FITTING NON-LINEAR CURVES BY LEAST SQUARES

Technical Report ·
OSTI ID:4186338

A prograrn has been written. for an IBM Type 704 Computer, which performs the functions common to all problems of obtaining least squares estimates of the parameters in non-linear functions. Thus, to solve a particular problem of this type, the user needs only to furnish a program in which the function being fitted and its derivatives are evaluated. Also, several other programs---an overflow/underflow procedure and function subroutines often used in curve fitting problems-have been modified for use with the Non-Linear Least Squares program.
