摘要： 地理坐标系(Geographic coordinate system)：就是椭球体的球面坐标系统。椭球体具有特点：具有长半轴，短半轴，偏心率。以经纬度线划分表面区域，和定位坐标。 投影坐标体系：实质上是一个平面坐标系统，就是将椭球体表面的空间坐标投影到一个平面上的坐标体系。就是我们常用的地图坐标。也 阅读全文

摘要： 大数定理 弱大数定理(辛钦大数定理) 设随机变量\(X_{1},X_{2},...X_{n}...\)相互独立，服从同一个分布且具有数学期望\(E(X_{k}) = \mu (k = 1,2,..)\)则序列$ \overline{X} = \frac{1}{n} \sum_{k = 1}^{n}X 阅读全文

摘要： 设总体\(X\thicksim N(\mu,\sigma^2)\)，\(\sigma^2\)为已知，\(\mu\)为未知的，设\(X_{1},X_{2}...X_{n}\)为总体\(X\)的样本，则求\(\mu\)的置信区间。 知道\(\overline{X}是无偏估计\)，且有 \[\frac{X 阅读全文
