Approximate Bayesian Computation in State Space Models

, 2014
A new approach to inference in state space models is proposed, based on approximate Bayesian computation (ABC). ABC avoids evaluation of the likelihood function by matching observed summary statistics with statistics computed from data simulated from the

Solving, Estimating and Selecting Nonlinear Dynamic Economic Models without the Curse of Dimensionality [PDF]

A welfare analysis of a risky policy is impossible within a linear or linearized model and its certainty equivalence property. The presented algorithms are designed as a toolbox for a general model class. The computational challenges are considerable and

Distributed multi‐station target tracking based on unscented particle filter and Dempster‐Shafer theory

IET Radar, Sonar & Navigation
In a distributed multi‐station system, the observations received by local radar nodes for a single target will have a large signal‐to‐noise ratio (SNR) bias due to inconsistent radar cross‐sections from distinct angles, different distances from the ...

Kalman Filter, Unscented Filter and Particle Flow Filter on Non-linear Models

, 2018
Filters, especially wide range of Kalman Filters have shown their impacts on predicting variables of stochastic models with higher accuracy then traditional statistic methods. Updating mean and covariance each time makes Bayesian inferences more meaningful. In this paper, we mainly focused on the derivation and implementation of three powerful filters:
