Dementia in Parkinson's Disease:Demographic Models and Estimates
Dementia Parkinson's Disease Demographic Models Estimates
2016/3/18
It is difficult to measure incidence and prevalence rates for rare conditions.For very rare conditions, the sample size requirements begin to approach the total population size. However, there is a ...

Organized and funded by the IUSSP Scientific Committee on Historical Demography in collaboration with the Inter-university Consortium for Political and Social Research, University of Michigan, USA, an...
A matrix approach to the statistics of longevity in heterogeneous frailty models
frailty heterogeneity individual stochasticity longevity Markov chains mortality
2014/11/27
Background: The gamma-Gompertz model is a fixed frailty model in which baseline mortality increases exponentially with age, frailty has a proportional effect on mortality, and frailty at birth follows...
A matrix approach to the statistics of longevity in heterogeneous frailty models
statistics of longevity heterogeneous frailty models
2014/11/27
To develop a matrix model to compute all the statistical properties of longevity from the
gamma-Gompertz and related models.
Point process models for household distributions within small areal units
areal units household distribution point processes simulation spatial demography
2014/11/20
Spatio-demographic data sets are increasingly available worldwide, permitting ever more realistic modeling and analysis of social processes ranging from mobility to disease transmission. The informati...
Demography, foreclosure, and crime:: Assessing spatial heterogeneity in contemporary models of neighborhood crime rates
demographic context and crime foreclosure and crime geographically weighted regression
2014/11/20
Background: The present research evaluates the possibility of spatial heterogeneity in the effects on neighborhood crime rates of both traditional demographic indicators - immigrant concentration, rac...
Studying historical occupational careers with multilevel growth models
careers growth models historical data
2010/10/14
In this article we propose to study occupational careers with historical data by using multilevel growth models. Historical career data are often characterized by a lack of information on the timing o...
Senescence vs. sustenance: Evolutionary-demographic models of aging
aging eusociality evolution fertility hydra mortality senescence sustenance
2010/10/14
Humans, and many other species, suffer senescence: mortality increases and fertility declines with adult age. Some species, however, enjoy sustenance: mortality and fertility remain constant. Here we ...
Long-range trends in adult mortality: Models and projection methods
long-range trends adult mortality projection methods
2009/9/15
This study has two objectives: (1) to test a new version of the logistic model for the pattern of change over time in age-specific adult mortality rates, and (2) to develop a new method for projecting...

Ethnic Models of Fertility Behaviour in Sri Lanka
Fertility Behaviour Sri Lanka Ethnic Models
2009/4/24
Sri Lanka's multi-ethnic society provides a useful example of how fertility behaviour can be affected by ethnic differences. This article elaborates on the possible sources, extent and nature of the v...
Workshop on “Age-structured models in population dynamics and economics”at the Vienna Institute of Demography, October 27-28, 2003
Age-structured models economics population dynamics
2009/3/19
The workshop brought together specialists in the theory and in different areas of
application of age- and/or duration-structured dynamical systems. Among those areas
are demography, population dyna...
Perturbation analysis of nonlinear matrix population models
age averages barnacles density-dependence dependency ratios elasticity homeostasis immigration matrix calculus matrix population models population cycles sensitivity Tribolium two-sex models
2008/12/16
Perturbation analysis examines the response of a model to changes in its parameters. It is commonly applied to population growth rates calculated from linear models, but there has been no general appr...
A simulation-based assessment of the bias produced when using averages from small DHS clusters as contextual variables in multilevel models
average bias clustering contextual DHS measurement error multilevel simulation size small
2008/12/12
There is much interest these days in the importance of community institutions and resources for individual mortality and fertility. DHS data may seem to be a valuable source for such multilevel analys...
Trajectories and models of individual growth
determinate development growth growth curve indeterminate life history model ontogeny
2008/12/12
It has long been recognized that the patterns of growth play an important role in the evolution of age trajectories of fertility and mortality (Williams, 1957). Life history studies would benefit from...
