title: Actual to expected studies--Part 2.
abstract: In Part I of this two-part series, we used a synthetic dataset which we called the "Health Risk Appraisal" dataset. Using this dataset, we performed an actual/expected mortality study using one and only one health assessment per individual. This synthetic dataset is actually more realistic in that many persons were evaluated more than once. Our previous study assessed predicted mortality based on the "first" HRA evaluation. There are three other alternatives: "last", "every", and "weighted-every" aka, "fractional". In this Part 2, we will briefly describe the "last" and "every" scenarios" and compare their results with those from the "first". We will then describe the fractional method in detail because our experience has shown this method provides the most desirable results.
