Exploratory data analysis for complex models.(Discussion Article)
December 1, 2004... "Exploratory" and "confirmatory" data analysis can both be viewed as methods for comparing observed data to what would be obtained under an implicit or explicit statistical model. For example, many of Tukey's methods can be interpreted as checks against hypothetical linear models and Poisson...

Discussion.(Discussion Article)
December 1, 2004... Gelman's article is a thought-provoking mix of opinions and creative methodology. I agree with Gelman that the disjunction of models and exploratory data analysis (EDA) in mainstream statistics is unsound. The assumption that models belong exclusively to confirmatory data analysis (CDA) is...

Rejoinder.(Discussion Article)
December 1, 2004... I appreciate Buja's generous comments and will briefly clarify some issues regarding the role of data visualization in model checking, and the relevance of Bayesian inference to model checking. 1. DATA VISUALIZATION My article presents four general kinds of model-based graphical...

Clustering visualizations of multidimensional data.
December 1, 2004... Many graphical methods for displaying multivariate data consist of arrangements of multiple displays of one or two variables: scatterplot matrices and parallel coordinates plots are two such methods. In principle these methods generalize to arbitrary numbers of variables but become difficult...

CARTscans: a tool for visualizing complex models.
December 1, 2004... We present CARTscans, a graphical tool that displays predicted values across a four-dimensional subspace. We show how these plots are useful for understanding the structure and relationships between variables in a wide variety of models, including (but not limited to) regression trees,...
