This code reproduces the comparison between the three algorithms considered in the publications [J18], [C70] and [C60]. Three examples of parameter inference are included;
- Linear Gaussian state space model (using bootstrap particle filtering with the filter smoother for estimating the Hessian).
- Linear Gaussian state space model (using fully-adapted particle filtering with the fixed-lag smoother for estimating the Hessian).
- Hull-White stochastic volatility model (using bootstrap particle filtering with the filter smoother for estimating the Hessian).
Python code
This code is written by Johan Dahlin and it is available here, see also Johan’s software page.
