Query: Application of a Second-order Stochastic Optimization Algorithm for
  Fitting Stochastic Epidemiological Models   Epidemiological models have tremendous potential to forecast disease burden
and quantify the impact of interventions. Detailed models are increasingly
popular, however these models tend to be stochastic and very costly to
evaluate. Fortunately, readily available high-performance cloud computing now
means that these models can be evaluated many times in parallel. Here, we
briefly describe PSPO, an extension to Spall's second-order stochastic
optimization algorithm, Simultaneous Perturbation Stochastic Approximation
(SPSA), that takes full advantage of parallel computing environments. The main
focus of this work is on the use of PSPO to maximize the pseudo-likelihood of a
stochastic epidemiological model to data from a 1861 measles outbreak in
Hagelloch, Germany. Results indicate that PSPO far outperforms gradient ascent
and SPSA on this challenging likelihood maximization problem.
