Studentized residual

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.
