Menu: View→Analysis Properties→Random #→Seed for random numbers
Specifies a seed for the Wichman-Hill (Wichman & Hill, 1982) random number generator that is used for bootstrapping and for the permutation test. Using Amos twice with the same seed guarantees getting the same sequence of random numbers both times.
For more information, see the Seed method of the AmosEngine class.
