    The unobserved heterogeneity distribution in duration analysis


    Abbring, JH & Berg, GJVD, 2007, ‘The unobserved heterogeneity distribution in duration analysis’. Biometrika, vol 94., pp. 87-99


    In a large class of hazard models with proportional unobserved heterogeneity, the distribution of the heterogeneity among survivors converges to a gamma distribution. This convergence is often rapid. We derive this result as a general result for exponential mixtures and explore its implications for the specification and empirical analysis of univariate and multivariate duration models.
