中文说明: 趋势面分析是拟合数学面的一种统计方法.具体的方法就是用数学方法计算出一个数学曲面来拟合数据中的区域性变化的"趋势",这个数学面叫做趋势面,方法的过程叫做趋势面分析. 是利用数学曲面模拟地理系统要素在空间上的分布及变化趋势的一种数学方法,实质上是通过回归分析原理,运用最小二乘法拟合一个二元非线性函数,模拟地理要素在空间上的分布规律,展示地理要素在地域空间上的变化趋势;
English Description:
Trend surface analysis is a statistical method of fitting mathematical surface. The specific method is to use mathematical method to calculate a mathematical surface to fit the "trend" of regional changes in the data. This mathematical surface is called trend surface, and the process of the method is called trend surface analysis
