The residuals which often used have ordi nary residualsδ i ?the internally studentized residuals r i and externally studentized residuals r i .
残差分析在回归诊断中十分重要,常用的残差有普通残差δi、内学生化残差ri和外学生化残差ri等。
Then based on the IGGⅢ?scheme which is suitable for numeration in the surveying field,the paper constructs equivalent weight function by studentized residual for robust estimation.
首先分析了现有几种等价权函数的优缺点,然后以适合于测量领域计算的IGGⅢ方案为基础,利用服从于t分布的学生化残差构造等价权函数来进行抗差估计。
An integrated method is given to judge clustering result and estimate clustering effect,which includes student residual,correlation coefficient and clustering dendrogram.
针对海上目标分群问题,介绍了反舰导弹对海上目标分群的两种常用的特征空间坐标及其特征标准化方法,提出了用相关系数、聚类树图和学生残差对海上目标分群进行聚类判定和综合检验的方法。
The student residual test method is put forward to estimate clustering effect.
结果表明,学生残差检验法是有效的,并且在W ard方法和欧几里德平方距离尺度下可以得到较好的聚类效果,针对具体应用选择合适的联接规则和距离尺度将有效提高层次化聚类效果。
