To be credible, a model such as HealthAgeingMod needs to be validated
against external benchmarks, its limitations need to be identified, and the extent of its
generalisability needs to be explained. To the extent possible, credibility should be
widely established among, for example, potential users, researchers, medical
practitioners, policy developers and health administrators. This Chapter summarises
work carried out to establish credibility, in addition to the work that had been reported
in a peer reviewed Journal [37].
Keywords: Model validation, alignment against benchmark statistics, base-year
and projection period output validations, model generalisability, limitattions,
credibility of results, potential users.
