Analysis of clinical trials — Failure to include all participants in the analysis may bias the trial results. Most trials do not yield perfect data, however. Protocol violations may occur, such as when the patients do not receive the full intervention or the correct… … Wikipedia
Post-hoc analysis — design and analysis of experiments, refers to looking at the data after the experiment has concluded for patterns that were not specified a priori . It is also known as data dredging to evoke the sense that the more one looks the more likely… … Wikipedia
Data analysis — Analysis of data is a process of inspecting, cleaning, transforming, and modeling data with the goal of highlighting useful information, suggesting conclusions, and supporting decision making. Data analysis has multiple facets and approaches,… … Wikipedia
Fitting subgroup — In mathematics, especially in the area of algebra known as group theory, the Fitting subgroup F of a finite group G , named after Hans Fitting, is the unique largest normal nilpotent subgroup of G . Intuitively, it represents the smallest… … Wikipedia

Restricted representation — In mathematics, restriction is a fundamental construction in representation theory of groups. Restriction forms a representation of a subgroup from a representation of the whole group. Often the restricted representation is simpler to understand … Wikipedia
