  1. ncbi Global tests in the additive hazards regression model
    Axel Gandy
    Department of Mathematics, Imperial College London, London, UK
    Stat Med 27:831-44. 2008
    ..This test is a natural extension of the logrank test. We shall also discuss an alternative covariance estimator. The tests are applied to a data set and a simulation study is performed...

    Axel Gandy
    Department of Mathematics, Imperial College London, London, UK
    Lifetime Data Anal 15:534-57. 2009
    ..We report results from several simulation studies and apply our test to a real dataset...
  3. ncbi Checking a semiparametric additive risk model
    Axel Gandy
    Institute for Applied Mathematics and Statistics, University of Hohenheim, 70593, Stuttgart, Germany
    Lifetime Data Anal 11:451-72. 2005
    ..The tests can be adjusted to detect particular alternatives. As one of the most important alternatives we consider Cox's proportional hazards model. We present simulation studies and an application to a real data set...
