EM Algorithm for Markov Chains Observed Via Gaussian Noise and Point Process Information : Theory and Case Studies

Damian, Camilla - 2017

In this paper we study parameter estimation via the Expectation Maximization (EM) algorithm for a continuous-time hidden Markov model with diffusion and point process observation. Inference problems of this type arise for instance in credit risk modelling. A key step in the application of the EM...
