"Confidence Regions for Simple Correspondence Analysis using the Cressi" by Asma A. Alzahrani, Eric J. Beh et al.
When examining the association between symmetrically associated categorical variables, correspondence analysis provides a visual means of identifying the structure of this association. An important and sometimes overlooked feature that can help the analyst determine whether these categories provide a statistically significant contribution to the association is the confidence region. When constructing these regions, correspondence analysis traditionally (but not always) considers Pearson’s chi-...
