1. 1. Statistical Inference for Traffic Safety Analysis Using the Generalized Pareto Distribution

   University essay from Lunds universitet/Matematisk statistik

   Author : Emilsson Sara; Filip Vestin; [2020]
   Keywords : Extreme value theory; traffic safety analysis; surrogate measure of safety; maximum likelihood; delta method; profile likelihood; modified profile likelihood.; Mathematics and Statistics;

   Abstract : This thesis investigates the possibility of computing interval estimates for metrics that pertain to traffic safety based on surrogate measures of safety. A probabilistic model of the (near) crash count is defined using the generalized Pareto distribution and three different methods for calculating confidence intervals for the corresponding intensity parameter are proposed.

3. 2. Stochastic Modelling of Train Delay Time Series in Skåne, Sweden

   University essay from Lunds universitet/Statistiska institutionen

   Author : Filip Vestin; Valentin Zulj; [2018]
   Keywords : Stochastic models; train delays; time series; Mathematics and Statistics;

   Abstract : The purpose of this paper is to provide a foundation for modelling train delays as multivariate time series. A pertinent issue with this kind of analysis is that the individual time series do not follow the Gaussian normal distribution. READ MORE
