Population Cluster Assignment Report - Batch Job Class
The Cluster Assignment Report for the population indicates how well the clusters represent all of the resource vectors. The report also provides an analysis of the resources that are consumed by the clusters. The resources detailed in this report are specified on the Workload Characterization screen (see Figure 11-18 in ).

The Cluster Assignment Report for the population indicates how well the clusters represent all of the resource vectors. The report also provides an analysis of the resources that are consumed by the clusters. The resources detailed in this report are specified on the Workload Characterization screen (see Figure 11-18 in Batch Job Class - Workload Characterization).
The representative hypothesis that was introduced in CAP Workload Characterization tests how close the resource vectors are to the characterization proposed for the workload. We propose to test this hypothesis by assigning the resource vectors for the full population to the clusters developed for the sample.
You can test this hypothesis by comparing the marginal assignment percentage for the sample of resource vectors, shown previously in Figure 11-17 in Inquiry Processing Screen, to the marginal assignment percentage for the full population shown in Figure 11-28. Since these two values are nearly the same (5.4% vs. 5.7%), you can consider the conditions of the representative hypothesis met. If the test had not been met, you would have repeated the procedure with a larger sample size.
