WebWe fit a logistic regression model and estimate the parameters using standard Markov chain Monte Carlo (MCMC) methods. Due to the weaknesses and limitations of the standard MCMC methods, we then perform model estimation in one special example of a Piecewise Deterministic Markov Process, named the Bouncy Particle Sampler (BPS).
