Some Interpretative Tools for Non-Symmetrical Correspondence Analysis

Bootstrap Confidence Regions in Non-symmetrical Correspondence Analysis

Non-symmetric Correspondence analysis is a method increasingly used in place of classical correspondence analysis to portray the asymmetric association of two categorical variables. In this paper we investigate the reliability of graphical displays illustrating variable prediction, by looking at inferential aspects of the sampling variation of the configuration of points, using a bootstrap appr...

Some Generalizations of Correspondence Analysis

Correspondence analysis of a bivariate table has many diierent opti-mality properties. For instance, the scores computed by correspondence analysis linearize both regressions, and maximize the correlation coee-cient. We try to generalize both properties to the multivariate situation, using the concept of maximizing any aspect of the correlation matrix, and the concept of simultaneously lineariz...

Deterministic and Probabilistic Models for Symmetrical and Non Symmetrical Principal Component Analysis

Being a non-drinking student: an interpretative phenomenological analysis.

Recent research suggests that safer student alcohol consumption might be assisted by understanding how social occasions are managed by non-drinkers. In-depth, semi-structured interviews with five 19-22 year old non-drinking English undergraduates were subjected to interpretative phenomenological analysis. We present five inter-linked themes: 'living with challenges to non-drinking'; 'seeing wha...
