Efficient Statistical Inference for Stochastic Reaction Processes
Andreas Ruttor, Manfred Opper · Physical Review Letters · 2009
We address the problem of estimating unknown model parameters and state variables in stochastic reaction processes when only sparse and noisy measurements are available. Using an asymptotic system size expansion for the backward equation, we derive an efficient approximation for this problem. We demonstrate the validity of our approach on model systems and generalize our method to the case when some state variables are not observed.
