With the observed information and some prior knowledge for a potential model, parameter estimation of an ODE model often requires a lot of computation works, such as a numerical integration of the ODE system and minimization of the log-likelihood function. In this paper, we consider a partially observed ODE model: 2D-HR type model. With the partially information, we present a simple way (iterative estimation process) without too mach computation to estimate the parameters in this model.參數估計微分方程模型類Hindmarsh-Rose模型parameter estimationordinary differential equationsHindmarsh-Rose Type modelpartially observed model
