Entropy of the Gompertz-Makeham mortality model
Gompertz-Makeham mortality life table entropy
2014/11/26
Background: Life table entropy is a quantity frequently used in demography; e.g., as a measure of heterogeneity in age at death, or as the elasticity of life expectancy with regards to proportional ch...
Investigating healthy life expectancy using a multi-state model in the presence of missing data and misclassification
cognitive function microsimulation misclassification panel data
2014/11/26
Background: A continuous-time three-state model can be used to describe change in cognitive function in the older population. State 1 corresponds to normal cognitive function, state 2 to cognitive imp...
Another 'futile quest'? A simulation study of Yang and Land's Hierarchical Age-Period-Cohort model
age period cohort models identification problem MCMC simulation Yang and Land
2014/11/26
Background: Whilst some argue that a solution to the age-period-cohort (APC) 'identification problem' is impossible, numerous methodological solutions have been proposed, including Yang and Land's Hie...
Reforging the Wedding Ring: Exploring a Semi-Artificial Model of Population for the United Kingdom with Gaussian process emulators
agent-based computational demography Gaussian process emulator multistate models population dynamics sensitivity analysis
2014/11/25
Background: We extend the "Wedding Ring‟ agent-based model of marriage formation to include some empirical information on the natural population change for the United Kingdom together with behav...
A dynamic birth-death model via Intrinsic Linkage
birth-death models cyclical stability dynamic population models Leslie matrices metastable
2014/11/24
Background: Dynamic population models, or models with changing vital rates, are only beginning to receive serious attention from mathematical demographers. Despite considerable progress, there is stil...
The “Wedding-Ring”An agent-based marriage model based on social interaction
age at marriage agent-based computational demography marriage micro-macro models social interaction
2008/12/16
In this paper we develop an agent-based marriage model based on social interaction. We build an population of interacting agents whose chances of marrying depend on the availability of partners, and w...
A general temporal data model and the structured population event history register
data, data model database DSS event influence longitudinal metadata methods population register relational SPEHR state surveillance temporal
2008/12/12
At this time there are 37 demographic surveillance system sites active in sub-Saharan Africa, Asia and Central America, and this number is growing continuously. These sites and other longitudinal popu...
A model for geographical variation in health and total life expectancy
disease burden healthy life expectancy life tables proportionality assumption spatial effects
2008/12/11
This paper develops a joint approach to life and health expectancy based on 2001 UK Census data for limiting long term illness and general health status, and on registered death occurrences in 2001. T...
