Guidelines for choosing between multi-item and single-item scales for construct measurement: a predictive validity perspective
Adamantios Diamantopoulos,Marko Sarstedt,Marko Sarstedt,Christoph Fuchs,Petra Wilczynski,Sebastian Kaiser +5 more
TL;DR: In this article, a comprehensive simulation study is conducted aimed at identifying the influence of different factors on the predictive validity of single versus multi-item measures, such as the average inter-item correlations in the predictor and criterion constructs, the number of items measuring these constructs, as well as the correlation patterns of multiple and single items between the predictor between the criterion constructs.

Biclustering: Overcoming Data Dimensionality Problems in Market Segmentation
TL;DR: In this article, the authors introduce biclustering, a novel approach to address the problem of high dimensionality in tourism segmentation studies, which aims to identify market segments among tourists who are similar to each other, thus allowing a targeted marketing mix to be developed.
Journal ArticleDOI
Robust biclustering by sparse singular value decomposition incorporating stability selection
TL;DR: The S4VD algorithm is proposed to incorporate stability selection to improve this method, which is the first biclustering approach that takes the cluster stability regarding perturbations of the data into account.
A toolbox for bicluster analysis in R
TL;DR: The R package biclust is introduced, which contains a collection of bicluster algorithms, preprocessing methods for two way data, and validation and visualization techniques for bicuster results.
