A method for visual identification of small sample subgroups and potential biomarkers
(2011) In Annals of Applied Statistics 5(3). p.2131-2149- Abstract
- In order to find previously unknown subgroups in biomedical data and
generate testable hypotheses, visually guided exploratory analysis can be of
tremendous importance. In this paper we propose a new dissimilarity measure
that can be used within the Multidimensional Scaling framework to obtain a
joint low-dimensional representation of both the samples and variables of a
multivariate data set, thereby providing an alternative to conventional biplots.
In comparison with biplots, the representations obtained by our approach are
particularly useful for exploratory analysis of data sets where there are small
groups of variables sharing unusually high or low values... (More) - In order to find previously unknown subgroups in biomedical data and
