Thesis or dissertation. Publisher. University of Exeter. Degree Title. PhD in Psychology. Abstract. Frailty in older adults is characterised as a vulnerable state, which predicts a range of health outcomes (e.g., injurious falls, institutionalisation, and mortality). The physiological and practical outcomes of frailty are recognised, but the psychosocial processes are largely unexplored so.

Frailty Data from the core survey and from the physical perfor-mance measures subsample (for the Biologic Syndrome model) were used to operationalize the three frailty models in the HRS (Tables 1, 2, and 3). Functional Domains Model. The original model in the ACS consisted of 16 self-report items grouped into four.

In this dissertation, we introduce a method employing a frailty model to identify longitudinal biomarkers or surrogates for a time to event outcome. Our method is an extension of earlier work by Wulfson, Tsiatis, and Song where it was assumed that the event times have the same baseline hazard. In our method, we allow random effects to be.

A binomial frailty model for gene marker data is specified and this is applied to empirical data in the last part of the thesis. The model combines both the genetic and demographic information together for determining the relative risk of a gene allele or genotype and in estimating the corresponding frequencies. A Two-step MLE has also been introduced, to obtain a non-parametric form of the.

This dissertation consists of three chapters. The first chapter builds a new series of dynamic copula models and studies the influence of macro variables on the dependence between assets. The second chapter develops a dynamic logistics regression model and investigates how systematic risk affects mortgage default. The third chapter uses the frailty model developed in chapter 2 to explore.

Frailty Model Dissertation

Frailties models, an extension of the proportional hazards model, are used to model clustered survival data. In some situations there may be competing risks within a cluster. When this happens the basic frailty model is no longer appropriate. Depending on the purpose of the analysis, either the cause-specific hazard frailty model or the subhazard frailty model needs to be used.

The FRAIL scale, Cardiovascular Health Study Frailty Screening Measure (CHS), Clinical Frailty Scale, Groningen Frailty Indicator (GFI), Tilburg Frail Indicator (TFI), and EFS are a few of the frailty assessments that have been frequently mentioned in the literature as valid measures of frailty (Table 1). However, there is a gap between the validity of those scales obtained through research.
