Rivista Italiana di Economia Demografia e Statistica Volume LXV n. 1 – Gennaio-Marzo 2011 1. Introduction ALTERNATIVE VARIANTS OF THE HELIGMAN-POLLARD MODEL Anna Maria Altavilla, Angelo Mazza, Antonio Punzo In demographic analysis and actuarial practice, the use of crude age-specific mortality rates is often deemed as not appropriate since the observed-data pattern may be intended as a single realization of a stochastic process. To cope with this issue, several graduation techniques have been proposed in literature, based on the assumption that if the number of individuals in the group on whose experience data are based were considerably larger, then the set of observed indicators would display a much more regular progression with age (Copas and Haberman, 1983). In detail, the relation between the crude rates and the true but unknown mortality rates may be summarized as where denotes noise due to random variation, age misstatement, etc.. Such random fluctuations are usually more evident when small area datasets are investigated or at ages in which mortality is itself rarer. In order to capture the underlying mortality pattern from the crude rates, a graduation function ) is used; ) aims at smoothing out irregularities in crude mortality rates . In analogy with the usual statistical modelling, the ) function can be specified parametrically (see, e.g. Debòn et al., 2005) or nonparametrically (see, e.g. Debòn et al., 2006). In the following, we will address a specific class of parametric models often employed by demographers, in which the function described as is , , (1)
