TLDR
In this paper, the behavior of the parameter estimates when using different estimation strategies was examined in correlated frailty models, and a strong dependence between the two parameter estimates (variance and correlation of frailties) in the multivariate correlated Frailty model was detected and analyzed in detail.Citations

Timing is Everything: Getting Students Back on Track to College Readiness in High School
TL;DR: This article examined a longitudinal cohort (n = 6443) of students in an urban, public school district in order to explore how districts and communities can redirect off-track high school students.
Journal ArticleDOI
Bayesian analysis of an inverse Gaussian correlated frailty model
TL;DR: A Bayesian analysis of a correlated frailty model is discussed in the context of inverse Gaussian frailty and an MCMC approach is adopted and the deviance information criterion is used to compare models.

The heritability of breast cancer: a Bayesian correlated frailty model applied to Swedish twins data.
TL;DR: It is concluded that genetic effects would explain globally almost 30% of the total variability of propensity to breast cancer and a model which includes dominance genetic effects (ADE model) is preferred for genetic and statistical reasons.

Institutional Merit-Based Aid and Student Departure: A Longitudinal Analysis
TL;DR: The authors explored the relationship between institutional merit aid and student departure from a statewide system of higher education and found that, once they account for self-selection to the extent possible, there was no significant relationship.

Comparison of Frailty Models for Acute Leukemia Data under Gompertz Baseline Distribution
David D. Hanagal,Richa Sharma +1 more
TL;DR: In this article, two different shared frailty regression models under the assumption of Gompertz as the baseline distribution were considered for the acute leukemia data and compared with a real life bivariate survival data set of acute leukemia remission times.

The impact of heterogeneity in individual frailty on the dynamics of mortality.
TL;DR: Calculations based on Swedish mortality data suggest that standard methods overestimate current life expectancy and potential gains in life expectancy from health and safety interventions, while underestimating rates of individual aging, past progress in reducing mortality, and mortality differentials between pairs of populations.

A model for association in bivariate life tables and its application in epidemiological studies of familial tendency in chronic disease incidence
TL;DR: In this article, a related model for association in bivariate survivorship time distributions is proposed for the analysis of familial tendency in disease incidence, which is related to more specifically epidemiological models.

Analysis of Multivariate Survival Data
TL;DR: This work presents a meta-modelling architecture for shared frailty models that combines single-state and multi-state models, and shows clear patterns in how these models are modified for recurrent events.

A Language and Program for Complex Bayesian Modelling
TL;DR: This work describes some general purpose software that is currently developing for implementing Gibbs sampling: BUGS (Bayesian inference using Gibbs sampling), written in Modula-2 and runs under both DOS and UNIX.

Regression with frailty in survival analysis.
C A McGilchrist,C W Aisbett +1 more
TL;DR: In studies of survival, the hazard function for each individual may depend on observed risk variables but usually not all such variables are known or measurable, so a model including frailty is fitted to such repeated measures of recurrence times.
