  • Dynamic analysis of multivariate failure time data 
    Aalen, Odd O.; Fosen, Johan; Weedon-Fekjær, Harald; Borgan, Ørnulf; Husebye, Einar (Research report / Forskningsrapport, 2004)
    We present an approach for analysing internal dependencies in counting processes. This covers the case with repeated events on each of a number of individuals, and, more generally, the situation where several processes are ...
  • Dynamic path analysis - a new approach to analyzing time-dependent covariates 
    Fosen, Johan; Ferkingstad, Egil; Borgan, Ørnulf; Aalen, Odd O. (Research report / Forskningsrapport, 2005)
    In this article we introduce a general approach to dynamic path analysis. This is an extension of classical path analysis to the situation where variables may be time-dependent and where the outcome of main interest is a ...
  • Path analysis for survival data with recurrent events 
    Fosen, Johan; Borgan, Ørnulf; Weedon-Fekjær, Harald; Aalen, Odd O. (Research report / Forskningsrapport, 2004)
    We propose a method for path analysis of survival data with recurrent events. By applying an additive model for the intensity, concepts like direct, indirect and total effects may be defined in an analogous way as for ...
