  • Estimation in a model with incidental parameters
  • 2002
  • Reports (other academic/artistic)abstract
    • We study the maximum likelihood method together with bootstrap analysis and other uncertainty measures in a situation with both structural and incidental parameters and a rather simple parametric setting. Our purpose is to study methods that can be generalised to and used in more complicated situations of similar nature.Two different approaches to the incidental parameters are treated, one deterministic and one random. Both approaches are shown to give similar results. When analysing the asymptotic properties of the estimator of the structural parameter, the profile likelihood, the delta method and the bootstrap analysis seem to be equally good in the deterministic case. The bootstrap also works well with a random interpretation of the incidental parameters.

  • Including driver characteristics in a model of relative collision safety
  • 2000
  • Reports (other academic/artistic)abstract
    • When the relative collision safety between different car makes has been estimated, it has been shown that a person's age and sex influence the injury risk in accidents that are otherwise similar. In an earlier work, relative collisionsafety in cars are studied. That model is now expanded by introducing parameters related to the driver's age and sex. Different models are compared and the "best" model is chosen by a likelihood-ratio-test. The estimated relative risks compensated for the driver's age and sex are compared to the relative risks without such information. The uncertainties of the different estimates are studied by a bootstrap analysis.
