Competing Risk Analysis (CRA) aims at the correct estimation of marginal probability occurrence an event in presence competing events. Many statistical approaches developed for CRA are limited by strong assumptions about underlying stochastic processes. To overcome these issues and to handle censoring, machine learning have designed specialized cost functions. However, not generalizable, comput...

Copyright: © 2017 INFORMS Abstract. Competing technologies in emerging industries create uncertainties that discourage supplier investments. Open technology can induce supplier investments, but may also lead to intensified future competition. In this paper, we study competing manufacturers’ open-technology strategies. We show that despite the risk of intensifying future competition, open techno...

OBJECTIVE To determine the risk of cancer-specific mortality (CSM) versus the competing risk of mortality by other causes (MOC) in patients with localised prostate cancer (LPC) treated with radical prostatectomy (RP). MATERIAL AND METHOD An observational cohort study of 982 patients with LPC treated with RP selected from our department's PC registry database. A competing risk analysis was per...

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. ...

INTRODUCTION Risk factor analyses for nosocomial infections (NIs) are complex. First, due to competing events for NI, the association between risk factors of NI as measured using hazard rates may not coincide with the association using cumulative probability (risk). Second, patients from the same intensive care unit (ICU) who share the same environmental exposure are likely to be more similar w...

A competing risk is an event (for example, death in the ICU) that hinders the occurrence of an event of interest (for example, nosocomial infection in the ICU) and it is a common issue in many critical care studies. Not accounting for a competing event may affect how results related to a primary event of interest are interpreted. In the previous issue of Critical Care, Wolkewitz and colleagues ...
