Computer-assisted qualitative data analysis software (CAQDAS) is a well-known acronym in qualitative research. Nowadays, qualitative researchers are inclined to apply such software for various purposes. Critiques of the use of CAQDAS in qualitative research focus on the term “analysis”, claiming that that the tool does little to analyze data. According to these critiques, some users of CAQDAS a...

Use of the grounded theory research method (GTM) is increasing across many fields of inquiry. Understanding the GTM and how to apply it is therefore a key task for researchers examining the possibility of using this method in their research. Since its introduction by Glaser and Strauss in 1967, GTM has evolved into two major streams, and there has been a continual debate about the choice betwee...

Ce papier présente un modèle génératif et son estimation permettant la visualisation de données binaires. Notre approche est basée sur un modèle de mélange de lois de Bernoulli par blocs et les cartes de Kohonen probabilistes. La méthode obtenue se montre à la fois parcimonieuse et pertinente en pratique.

Visualizing large data by the SOM and GTM methods – what are we obtaining? Anna Bartkowiak University of Wrocław, Institute of Computer Science, Przesmyckiego 20, Wrocław 51–151, PL Abstract We consider the visualization of multivariate data yielded by the SOM and the GTM methods. Special emphasis is put on the position of outliers and extreme points. When evaluating four data sets, it is found...
