摘要
基于灰色直接建模法,提出了估计Lotka-Volterra模型参数的一种方法,较好的反映了相互影响的两个变量之间的互惠、竞争等关系,为定性预测分析提供了实证支持,并得到了定量预测的结果.实例说明本模型的有效性和适用性.并证明了数乘交换不影响原始序列的模拟精度,为解决灰色预测模型的病态性提供了思路.
This paper proposes a method for estimation the parameters of Lotka-Volterra model based on the grey direct modeling, it can better reflect the relationship between two variables, and provide empirical support for qualitative prediction analysis and obtain quan- titative results. This model is applied to analysis one practicable example, it has shown that this method is effective and applicable. This study indicates the multiple transformations can＇t change the precision of the simulation value, it presents a method to solve the morbidity problem of the matrix.
