| Abstract: | T-type estimation is a new kind of robust estimations,which takes t-distribution as the error distribution and has some advantages in some respects.The equivalent weight form of t-type estimation is presented.A disadvantage of t-type estimation that it cannot resist ill-conditioning is analyzed.To overcome this drawback,according to the idea of the generalized shrunken type robust estimation,the generalized shrunken t-type estimation is presented,which shrinks the solution of the location parameters.Some im... |
| Keywords: | gross errors t-type estimation robust biased estimations generalized shrunken type robust estimation generalized shrunken t-type estimation |
