Letter to the editor : on the term 'interaction' and related phrases in the literature on random forests


Boulesteix, Anne-Laure; Janitza, Silke; Hapfelmeier, Alexander; Van Steen, Kristel; Strobl, Carolin (2015). Letter to the editor : on the term 'interaction' and related phrases in the literature on random forests. Briefings in Bioinformatics, 16(2):338-345.

Abstract

In an interesting and quite exhaustive review on Random Forests (RF) methodology in bioinformatics Touw et al. address-among other topics-the problem of the detection of interactions between variables based on RF methodology. We feel that some important statistical concepts, such as 'interaction', 'conditional dependence' or 'correlation', are sometimes employed inconsistently in the bioinformatics literature in general and in the literature on RF in particular. In this letter to the Editor, we aim to clarify some of the central statistical concepts and point out some confusing interpretations concerning RF given by Touw et al. and other authors.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
