Time starts at time t =1, when z 0 is given. We draw a sequence, y t,,y T, from a … This paper considers stochastic simulations with correlated input random variables having NORmal-To-Anything (NORTA) distributions.

Realizations of these random variables are generated and inserted into a model of the system. Outputs of the model are recorded, and then the process is repeated with a new set of random values.

As an application, in section 4 we modelled the patient flow through chronic diseases departments. Admissions are modelled as a Poisson process with parameter (the arrival rate) estimated by using the observed Stochastic simulation has been frequently employed to assess water resources systems and its influences from climatic variables using time series models, including parametric models, such as autoregressive (AR) model (Lee, 2016), or nonparametric models (Lall and Sharma, 1996, Prairie et al., 2005, Lee et al., 2010). Stochastic modeling simulates reservoir performance by use of a probabilitydistribution for the input parameters.

Modeling and identification of dynamic systems

We assume that the simulation analyst does not know the marginal distribution functions and the base correlation matrix of the NORTA Usually, the underlying simulation model is stochastic, so that the objective function must be estimated using statistical estimation techniques (called output analysis in simulation methodology). Once a system is mathematically modeled, computer-based simulations provide information about its behavior. 8 STOCHASTIC SIMULATION 61 In general, quadrupling the number of trials improves the error by a factor of two.

synthetic datasets under the stochastic-on-stochastic valuation framework while the paper [17] is about creating synthetic datasets for valuation only at time zero. The remaining part of this paper is structured as follows. Section2presents a nested stochastic simulation engine for valuing the guarantees embedded in variable annuities.
