Comparisons of proportions in k dose groups against a negative control assuming order restriction: Williams-type test vs. closed test procedures

Authors: Ludwig A. Hothorn

arXiv

The comparison of proportions is considered in the asymptotic generalized linear model with the odds ratio as effect size. When several doses are compared with a control assuming an order restriction,...

Outlier-robust Kalman Filter in the Presence of Correlated Measurements

Authors: Hongwei Wang, Yuanyuan Liu, Wei Zhang, Junyi Zuo

arXiv

We consider the robust filtering problem for a state-space model with outliers in correlated measurements. We propose a new robust filtering framework to further improve the robustness of conventional...
