Subgroup Correspondences [PDF]
Proceedings of the Edinburgh Mathematical Society, 2018 AbstractFor a closed subgroup of a locally compact group the Rieffel induction process gives rise to aC*-correspondence over theC*-algebra of the subgroup. We study the associated Cuntz–Pimsner algebra and show that, by varying the subgroup to be open, compact, or discrete, there are connections with the Exel–Pardo correspondence arising from a cocycle,

The lack of statistical power of subgroup analyses in meta-analyses: a cautionary note
Epidemiology and Psychiatric Sciences, 2021 One of the most used methods to examine sources of heterogeneity in meta-analyses is the so-called ‘subgroup analysis’. In a subgroup analysis, the included studies are divided into two or more subgroups, and it is tested whether the pooled effect sizes ...

Propensity score weighting for causal subgroup analysis [PDF]
Statistics in Medicine, 2020 A common goal in comparative effectiveness research is to estimate treatment effects on prespecified subpopulations of patients. Though widely used in medical research, causal inference methods for such subgroup analysis (SGA) remain underdeveloped ...

Finite groups in which every self-centralizing subgroup is nilpotent or subnormal or a TI-subgroup [PDF]
, 2021 summary:Let $G$ be a finite group. We prove that if every self-centralizing subgroup of $G$ is nilpotent or subnormal or a TI-subgroup, then every subgroup of $G$ is nilpotent or subnormal. Moreover, $G$ has either a normal Sylow $p$-subgroup or a normal

Associations of Meningioma Molecular Subgroup and Tumor Recurrence.
Neuro-Oncology, 2020 BACKGROUND We and others have identified mutually-exclusive molecular subgroups of meningiomas, however, the implications of this classification for clinical prognostication remain unclear.

An Empirical Study of Rich Subgroup Fairness for Machine Learning [PDF]
FAT, 2018 Kearns, Neel, Roth, and Wu [ICML 2018] recently proposed a notion of rich subgroup fairness intended to bridge the gap between statistical and individual notions of fairness. Rich subgroup fairness picks a statistical fairness constraint (say, equalizing

Outcome Based Subgroup Analysis: A Neglected Concern. [PDF]
, 2009 A subgroup of clinical trial subjects identified by baseline characteristics is a proper subgroup while a subgroup determined by post randomization events or measures is an improper subgroup.
