灰色预测模型称为CM模型，G为grey的第一个字母，M为model的第一个字母。GM（1，1）表示一阶的，一个变量的微分方程型预测模型。GM（1，1）是一阶单序列的线性动态模型，主要用于时间序列预测。 一、GM（1，1）建模 设有数列 共有 个观察值 对 作累加生成，得到新的数列 ，其元素 （5-1） 有： 对数列 ，可建立预测模型的白化形式方程， （5-2） 式中： ——为待估计参数。分别称为发展灰数和内生控制灰数。设 为待估计参数向量 则 按最小二乘法求解， 有： （5-3） 式中： （5-4） （5-5） 将（5-3）式求得的 代入（5-2）式，并解微分方程，有 （1，1）预测模型为： （5-6）(gray forecasting model called CM model, the G-gray of a letter, the M model for the first letter. GM (1,1), a band of a variable type of differential equation models. GM (1,1) is a sequence of single-band linear dynamic model, mainly for time series prediction. A GM (1,1) model series with a total value of observation for the cumulative production, to a new series of its elements (5-1) : The series, we can establish the prediction model albino form of equation (5-2) where :-- to question the estimated parameters. The development will be known as the gray and hygiene control within a few gray. Set parameters to be estimated according to Vector least squares method, are : (5-3) where : (5-4) (5-5) (5-3) that obtained in lieu of income (5-2)- and solutions differential equations, (1 1) Fore)

说明：  在vc++ 环境下对mapinfo的mif mid数据格式的文件进行操作（本程序附带部分数据方便大家学习）本程序不仅对道路、 等高线、 电力层、 独立地物、居民地、水系、图廓线等图层进行显示，而且实现了 缩放 漫游 开窗放大等基本的功能.是研究mapinfo数据格式的一个很好参考源码。 (In vc++ environment for mapinfo data format of the mif mid file operations (part of the data included in this program to facilitate them to learn) This program not only for the roads, contour lines, power level, independent surface features, the residents, the water system, figure profile and other layers to display, but also achieved roaming window zoom zoom and other basic functions. mapinfo data format is to study a good reference source.)
