Changing the random seed for record selection
The random seed represents the starting point that Campaign uses to select records randomly.
If you are selecting records randomly, there are times when you might want to change the random seed. For example:
*
Your random sample is producing highly skewed results (for example, if all males in your data fall into one group and all females into another).
*
You have the same number of records in the same sequence, and using the same seed value each time that you run this process results in records being created into the same samples.
Follow the steps below to generate a different starting point for random record selection.
1.
Click the Cell Size Limit tab of a process configuration dialog.
2.
Use one of the following methods:
*
Enter a numeric value in the Random Seed text box.
*
Click the Pick button to randomly select a new seed value.
