DOI: 10.1002/asmb.70039

Abstract: Repairable systems, crucial in reliability studies, are characterized by recurrent failure times modeled as counting processes with intensity functions. This paper explores models for these failure times incorporating imperfect repairs, addressing unobserved heterogeneity via shared… read more here.

DOI: 10.1038/s41598-025-17991-2

Abstract: Epilepsy remains a significant global health concern with increasing prevalence and incidence. This study aimed to model the time to first remission among epilepsy patients at Jimma University Medical Center, Ethiopia, using parametric shared frailty… 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: 10.1155/2022/5760662

Abstract: Introduction The primary effect of the fertility process is the birth of the first child. The ages at which women establish marital union and give their first birth depend on and result in varying demographic… read more here.

DOI: 10.1186/s12874-021-01424-5

Abstract: Background The purpose of this research was to see how the k-means algorithm can be applied to survival analysis with single events per subject for defining groups, which can then be modeled in a shared… 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.
