利用多分类Logistic回归进行土地利用变化模拟——以湖北省嘉鱼县为例
Modeling Land Use Change Using Multinomial Logistic Regression
-
摘要: 提出了模拟土地利用变化的多分类Logistic回归模型,即将因变量的二分类扩展为多分类。分别计算各种类型之间的转换回归系数可提高模拟的精度。对于不同的土地利用类型,计算出了不同的回归系数。该模型用于研究湖北省嘉鱼县土地利用变化的正确率为73.4%。Abstract: We discuss multinomial logistic regression for land use change.Binary logistic regression could be extended to multinomial logistic regression,which exists to handle the case of dependents with more classes than two.Coefficients for each land use types are calculated and also used for prediction of competition.The result shows that the simulation in case of Jiayu County with correct percentage of 73.5% is satisfying.
