Poisson/gamma random field models for spatial statistics
Robert L. Wolpert,Katja Ickstadt +1 more
TL;DR: In this article, Doubly stochastic Bayesian hierarchical models are introduced to account for uncertainty and spatial variation in the underlying intensity measure for point process models, which are applied to a problem in forest ecology.
Journal ArticleDOI
Role of thioredoxin reductase 1 and thioredoxin interacting protein in prognosis of breast cancer
Cristina Cadenas,Dennis Franckenstein,Dennis Franckenstein,Marcus Schmidt,Mathias Gehrmann,Matthias Hermes,Bettina Geppert,Wiebke Schormann,Lindsey Maccoux,Lindsey Maccoux,Markus Schug,Anika Schumann,Christian Wilhelm,Evgenia Freis,Katja Ickstadt,Jörg Rahnenführer,Jörg Ingo Baumbach,Albert Sickmann,Jan G. Hengstler +18 more
TL;DR: TXNRD1 and TXNIP are associated with prognosis in breast cancer, and ERBB2 seems to be one of the factors shifting balances of both factors of the redox control system in a prognostic unfavorable manner.
Journal ArticleDOI
Improved criteria for clustering based on the posterior similarity matrix
Arno Fritsch,Katja Ickstadt +1 more
TL;DR: New criteria for estimating a clustering, which are based on the posterior expected adjusted Rand index, are proposed and are shown to possess a shrinkage property and outperform Binder's loss in a simulation study and in an application to gene expression data.

Identification of SNP interactions using logic regression
Holger Schwender,Katja Ickstadt +1 more
TL;DR: In this paper, logic regression is used to identify SNP interactions explanatory for the disease status in a case-control study and propose two measures for quantifying the importance of these interactions for classification, which are then applied to the SNP data of the GENICA study, a study dedicated to the identification of genetic and gene-environment interactions associated with sporadic breast cancer.
