Outliers in models with constraints

Lubomír Kubáček (2006)

Kybernetika

Similarity:

Outliers in univariate and multivariate regression models with constraints are under consideration. The covariance matrix is assumed either to be known or to be known only partially.

Linear model with inaccurate variance components

Lubomír Kubáček (1996)

Applications of Mathematics

Similarity:

A linear model with approximate variance components is considered. Differences among approximate and actual values of variance components influence the proper position and the shape of confidence ellipsoids, the level of statistical tests and their power function. A procedure how to recognize whether these diferences can be neglected is given in the paper.
