Abstract:
|
An analysis of customer survey data using direct and reverse regression led to some counter-intuitive conclusion. The phenomenon is known as the regression paradox. We describe sufficient conditions when the regression paradox will appear both analytically and geometrically. In linear models, it is a result of a distribution shift among groups relative to predictability in regression and reverse regression.
