PARAMETER ESTIMATION FOR LOTKA-VOLTERRA COMPETITION MODEL WITH RANDOM PERTURBATIONS

本文研究了两种群随机Lotka-Volterra竞争模型的参数估计的问题.利用最小二乘法，获得了点估计及（1-α）置信区间估计，同时得到了影响置信区间长度的因素.最后给出数值模拟，结果表明该方法的可行性与有效性.
In this paper, the problem of parameter estimation for two species stochastic Lotka-Volterra competition model is studied. By using the method of least squares, we obtain the point estimate and the (1 -α) confidence interval, and we get the factors which influence the confidence interval length. Finally, the numerical simulation results show that the method is feasible and effective
