Statistical Learning in Actuarial Applications WP

Aims

Our aim is to construct highly flexible actuarial models such as:

  • finite mixture regression models for the number and the costs of claims;
  • univariate and multivariate regression models with varying dispersion and shape for claim frequencies and severities;
  • copula based models with regression structures on the mean, dispersion and dependence parameters for different claim types and their associated claim counts and costs;
  • dependence modelling in risk management and sensitivity analysis;
  • first-order integer valued autoregressive INAR(1) regression models with varying dispersion for time series of claim counts;
  • neural network embeddings of the aforementioned models which are able to capture the stylized characteristics of structured, semi-structured and unstructured insurance data;
  • Classification of green bonds using statistical learning methods and decarbonization;
  • Gaussian process spatial-temporal regression models; and
  • Heavy tails and Extremes in spatial and temporal settings.
