Bayesian Estimation
maintains a log of previous seeds used, so it is possible to match the file creation dates
of previously generated analysis results or imputed datasets with the dates reported in
the Seed Manager.
Changing the Current Seed
E Click Change and enter a previously used seed before performing an analysis.
Amos will use the same stream of random numbers that it used the last time it started
out with that seed. For example, we used the Seed Manager to discover that Amos used
a seed of 14942405 when the analysis for this example was performed. To generate the
same Bayesian analysis results as we did:
E Click Change and change the current seed to 14942405.
The following figure shows the Seed Manager dialog box after making the change:
A more proactive approach is to select a fixed seed value prior to running a Bayesian
or data imputation analysis. You can have Amos use the same seed value for all
analyses if you select the
Always use the same seed option.
