Generating Sample Fill-in

If a run does not find the required sample using the specified weight set, you can execute a "topping-up" run for which weights are recalculated automatically to generate the required total sample. The new weights are calculated based on the difference between the specified target and the outcome of the previous run.

1. On the Execution tab > Job Runs list, select the run you wish to top-up.
2. Click Generate Sample Fill-in.

A confirmation window opens - .

3. Click OK to continue.

The sub-sample target is changed to what is missing from the original sample, the sub sample weights are changed to ensure the required sample is achieved, the matrix used by the sub-sample is given new weights and the weight targets are updated. The job is then run and the sample will be completed.
