Bootstrapping Aalen-Johansen processes for competing risks: Handicaps, solutions, and limitations

Posterior concentration rates for counting processes with Aalen multiplicative intensities

Competing risks.

Consider a unit which can experience any one of k competing failure types, and suppose that for each unit we observe the time to failure, T , and the type of failure, C ∈ {1, 2, . . . , k}. The case of observing the pair (T, C) is termed “competing risks” in the statistical literature. After considering some examples we review basic notation and theory of competing risks. In particular we consi...

Parametric Estimation in a Recurrent Competing Risks Model

A resource-efficient approach to making inferences about the distributional properties of the failure times in a competing risks setting is presented. Efficiency is gained by observing recurrences of the compet- ing risks over a random monitoring period. The resulting model is called the recurrent competing risks model (RCRM) and is coupled with two repair strategies whenever the system fails. ...

Risks, Limitations and the Need for Additional Measures Against Ransomware in the Health Information Technology Infrastructure

Introduction: Even before the Covid 19 pandemic, one of the lucrative targets for attackers behind ransomware attacks was Encroaching on the continuity of services in the field of health information technology. In this study, for the first time, while introducing, relying on statistics and modeling, it is shown that the prevention and counteraction of these attacks in the IT infrastructure of t...

Competing risks and multistate models.

Complex clinical endpoints are present in studies in cancer. Especially in studies on hematopoietic stem-cell transplantation (HSCT), various risks exist after HSCT. Patients can experience acute and chronic graft versus host disease (GVHD) or need to undergo immunosuppressive therapy (IST), a relapse can occur, or patients can die after relapse or without former relapse (nonrelapse mortality, ...
