| 摘 要： | 在分析一维观测量、二维和三维坐标点置信区间、区域的基础上，利用几个重要的数学分布，导出了线、面这一ｐ维随机向量的置信区域——ｐ维超空间误差椭球半径的计算公式，同时应用实例验证了该通式与常规公式的一致性。这不仅为ＧＩＳ中线、面的精度评定提供了一个指标，而且为任意ｐ维随机向量在不同置信度下、置信区间大小的确定提供了一个通用公式

| Abstract: | Basing on the analysis of 1 dimension observation,2 dimensions and 3 dimensions points confidence region,a general formular is proposed in this paper,which can be used to calculate the semidiameter of P dimensions super space ellisposid by using some important probability distributions.Some example results show that it is consistent with current formular.So it not only provides an index for assessing the accuracy of line and polygon but also give a formular which can determine the size of confidence region for any dimension or any confidence extent. |

| Keywords: | random vector confidence extent confidence region ellisposid probability |
