DOI: 10.1002/sim.9667
Abstract: This article focuses on shared frailty models for correlated failure times, as well as joint frailty models for the simultaneous analysis of recurrent events (eg, appearance of new cancerous lesions or hospital readmissions) and a… read more here.

DOI: 10.1007/s00362-015-0697-8
Abstract: In this paper, relative behavior of two frailty models with different frailty variables and a common baseline variable are considered. We show that, under some conditions on frailty variables, the ratio of the hazard rate… read more here.

DOI: 10.1007/s11113-019-09524-3
Abstract: Racial/ethnic disparities in grade retention related to structural inequality are investigated using a quantitative theoretical model from the health literature. Data from the Early Childhood Longitudinal Study-Kindergarten Cohort are linked with segregation indices for dissimilarity… read more here.

DOI: 10.1016/j.archger.2021.104515
Abstract: INTRODUCTION Social frailty is a complex concept and there is still no consensus on the criteria that best define it, nor on the role that social dimensions play in well-established frailty models. AIM To analyse… read more here.

DOI: 10.1016/j.jspi.2018.10.002
Abstract: Abstract In this paper, we propose an extension of the frailty modeling to analyze the recurrent events data. We proposed a class of models, based on nonlinear mixed effects modeling, that takes into consideration of… read more here.

DOI: 10.1080/02664763.2019.1601688
Abstract: ABSTRACT In clustered survival data, the dependence among individual survival times within a cluster has usually been described using copula models and frailty models. In this paper we propose a profile likelihood approach for semiparametric… read more here.

DOI: 10.1080/03610926.2014.990102
Abstract: ABSTRACT The unknown or unobservable risk factors in the survival analysis cause heterogeneity between individuals. Frailty models are used in the survival analysis to account for the unobserved heterogeneity in individual risks to disease and… read more here.

DOI: 10.1177/0962280218803127
Abstract: Frailty models have been developed to quantify both heterogeneity as well as association in multivariate time-to-event data. In recent years, numerous shared and correlated frailty models have been proposed in the survival literature allowing for… read more here.

DOI: 10.1371/journal.pone.0271883
Abstract: Background Leprosy is an illness persisting for a long time or constantly recurring brought about by Mycobacterium leprae. The collusion of the causing agent with Schwann cells leads to incapable of being changed loss of… read more here.
