ORBi Open Repository and Bibliography (324.361 recursos)

In may 2007, the ULg's Administrative Board (joined in June 2007 by the FUSAGx) decided to create an institutional repository and defined a strong institutional self-archiving policy to increase the visibility, accessibility and impact of the University's publications (Board's decision). This decision led to the official launch, in November 2008, of the ORBi platform including both the Academic Bibliography and the Institutional Repository of the Wallonia-Europe University Academy.

  3. Variable selection in proportional hazards cure model with time-varying covariates, application to US bank failures

    Beretta, Alessandro
    From a survival analysis perspective, bank failure data are often characterised by small default rates and heavy censoring. This empirical evidence can be explained by the existence of a subpopulation of banks likely immune from bankruptcy. In this regard, we use a mixture cure model to separate the factors with an influence on the susceptibility to default from the ones affecting the survival time of susceptible banks. We extend a semi-parametric proportional hazards cure model to time-varying covariates and we propose a penalized-likelihood variable selection technique. By means of a simulation study, we show how this technique performs reasonably well....
