Résumé de these:

The growing challenges linked to the rapid increase of the world
population, especially at older ages, have recently stimulated
renewed attention to the development of innovative models to portray
and forecast human mortality. Sharp mortality declines observed
during the last centuries have indeed triggered a fast acceleration of
population growth since the beginning of the nineteenth century
(Maddison 2006). Additionally, virtually every country in the world is
experiencing growth in the number and proportion of older persons,
which creates funding problems for social security and healthcare
provision (Booth 20006; United Nations 2015).

This dissertation aims to bring new insights on the analysis and
forecast of human mortality by introducing novel statistical methods
that offer novel perspectives on mortality developments.

The first chapter proposes a re-parametization of classic model of
human mortality into a general and flexible family of models. The
proposed location-scale family is characterized by two parameters
that have a direct demographic interpretation, which allow to easily
interpret and compare mortality developments across different
populations.

From the second to the fourth chapters, the attention is shifted to the
age-at-death distribution, which is a very useful but surprisingly
neglected function for the analysis and forecast of human mortality.
Specifically, the second chapter introduces a relational model that
allows to capture and forecast adult mortality developments by
transforming the age-axis of a time-invariant distribution. In the third
chapter, the methodology is generalized and extended to the entire
age-range, thus including changes occurring to the childhood and
early adulthood components of mortality. The fourth chapter
presents an additional generalization of the methodology for the
analysis of cohort mortality data; in particular, mortality forecasts for
cohorts with partially observed data are presented and compared.

Finally, the fifth chapter proposes a new extension of the seminal
Lee-Carter model, which allows to decompose and forecast mortality
changes for the three components of human mortality already
analyzed in the third chapter.
