An empirical analysis of the importance of controlling for unobserved heterogeneity when estimating the income-mortality gradient
unobserved heterogeneity income-mortality gradient
2014/11/27
Statistical theory predicts that failing to control for unobserved heterogeneity in a
Gompertz mortality risk model attenuates the estimated income-mortality gradient
toward zero.
An empirical analysis of the importance of controlling for unobserved heterogeneity when estimating the income-mortality gradient
income mortality proportional hazard model unobserved heterogeneity

Background: Statistical theory predicts that failing to control for unobserved heterogeneity in a Gompertz mortality risk model attenuates the estimated income-mortality gradient toward zero.Objective...
Unobserved population heterogeneity: A review of formal relationships
gamma-distributed frailty Gompertz-Makeham force of mortality relative-risk models unobserved heterogeneity
2014/11/27
Background: Survival models accounting for unobserved heterogeneity (frailty models) play an important role in mortality research, yet there is no article that concisely summarizes useful relationship...
Unobserved population heterogeneity: A review of formal relationships
formal relationships population heterogeneity
2014/11/27
We present a list of important mathematical relationships that govern populations in
which individuals differ from each other in unobserved ways. For some relationships
we present proofs that, albei...
Heterogeneity's ruses: How hidden variation affects population trajectories of age-dependent fecundity in Drosophila melanogaster
Drosophila fecundity heterogeneity plateau reproductive life span senescence simulation
2014/11/26
Background: Progress in understanding senescence requires information about age-dependent changes in individual organisms. However, for experimental systems such as Drosophila melanogaster we usually ...
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...
Heterogeneity in the Strehler-Mildvan General Theory of Mortality and Aging
Heterogeneity in the Strehler-Mildvan General Theory Mortality and Aging
2014/3/20
This study examines and further develops the classic Strehler-Mildvan (SM) general theory of mortality and aging. Three predictions from the SM theory are tested by examining the age dependence of mor...
Constant global population with demographic heterogeneity
average age Cauchy-Schwarz inequality constant population heterogeneity life expectancy migration pensions population projection stationary population zero population growth
2008/12/16
To understand better a possible future constant global population that is demographically heterogeneous, this paper analyzes several models. Classical theory of stationary populations generally fails ...
Political Economy and Life Course Patterns The Heterogeneity of Occupational, Family and Household Trajectories of Young Spaniards
delayed transition to adulthood life course postponement of family formation sequence analysis Spain young adults
2008/12/1
We explore the strong linkages between macro changes and the dynamics of educational, occupational, family, and residential careers of young Spanish adults born between 1945 and 1974. We review theory...

census heterogeneity small area estimation census adjustment
2008/11/28
A sample covering 204,394 blocks from the 1990 U.S. Census permits measurement of residual heterogeneity from local area to local area after controlling by stratification for demographic characteristi...
