"Reinventing Regression Thru Graphics"

ABSTRACT

This talk is on an emerging theory for regression that provides a context which links regression with the construction, characterization and interpretation of graphical displays of the data. One underlying premise is that the usefulness of modern graphical displays might be increased substantially if we can recognize situations in which low-dimensional views, the only ones that are possible in practice, provide full or "sufficient" information about the regression. The ability to recognize such situations requires a context for connecting the graphics with the statistics.

For this purpose, regression is viewed quite broadly as the study of the conditional distribution of the response given the predictors. The context is similarly broad, requiring few scope-limiting conditions. The focus will be on fundamental ideas, and likely practical benefits, rather than on particular implementations or methods. The presentation will include examples.
