摘要
在传统的马尔科夫链基础上,构建了一种加权的马尔科夫预测模型。以1980-2009年的全国粮食产量作为基础数据,运用该方法对2010-2013年的粮食产量进行模型仿真和检验。实验结果表明,与传统的马尔科夫链相比,加权的马尔科夫链方法的误差更小,精度更高。
A new weighted Markov Model has been built based on the traditional Markov chain. At the same time, simulation and test were completed by using this weighted Markov chain through using the data of the Grain Production from 2010 thru 2013 based on the data of the Grain Production from 1980 thru 2009. The experimental results show that there is smaller error and higher accuracy of the predictions comparing with the traditional Markov chain.
