AU - Nelson, Barry L. PY - 1995. Abstract. Stochastic modeling develops a mathematical or financial model to simulate an entire system and derives a set of possible outcomes with its probability distribution. One of the benefits of a stochastic model is making uncertainty explicit. What is Stochastic Modeling? A model is stochastic if it has random variables as inputs, and consequently also its outputs are random. Y1 - 1995. We also proposed two stochastic models for the circadian system of Drosophila and simulated the dynamics of the system. The random variation is usually based on fluctuations observed in historical data for a selected period using standard time-series techniques. Then the assumptions that lead to the three dierent stochastic models are described in Sects.3.3, 3.4, and 3.5. Research on stochastic models develops and analyzes models of systems with random behavior. The result shows that the proposed method can describe the complex system more comprehensively, and the survival probability of the target is higher by introducing qualitative models into quantitative simulation.
