A Computer Program for Nonlinear Regression Using Least Squares.
NTIS: PB 237 036 :50 pages
The Bureau of Mines, at its Denver, Colorado, Research Center, has developed a computer program to solve nonlinear regression problems. The program is written in a general form so that regardless of the functional relationship assumed, the unknown parameters may be evaluated by the Newton-Raphson Method of iteration. Variances and covariances of the parameters are derived, based on the propagation of errors. A creep function is established from shale test data as an example of program utility. Program accuracy is compared with the accuracies of other programs in present-day use.
