Application of generalised linear model for time-dependent trend assessment—A case study for the ageing PSA network

The paper presents the results of a case study on “Investigation of component age-dependent reliability models” conducted under European Commission Joint Research Centre Ageing Probabilistic Safety Assessment Network Task 4 activities. Several Generalised Linear Model cases were applied and investigated in relation to both continuous and discrete data. The Fisher's χ 2 minimisation approach was used for goodness of fit testing and parameters elaboration. Finally, uncertainty analysis was done for parameters estimation and model extrapolations. The results were analysed and compared with other approaches. Engineering considerations are beyond the scope of the present study.
