IBM® SPSS® Amos™ 28

To use the Gauss-Newton method, rather than the Newton-Raphson method, for minimizing the discrepancy function:

1.Press (Menu: View→Analysis Properties).

2.Select the Numerical tab

3.Enter a positive integer in the Number of Gauss-Newton iterations box. This is the number of Gauss-Newton iterations that will be performed before Newton-Raphson iterations commence.

In an Amos program, use the Fisher method of the AmosEngine class.
