In statistics, a regression diagnostic is one of a set of procedures available for regression analysis that seek to assess the validity of a model in any of a number of different ways. This assessment may be an exploration of the model's underlying statistical assumptions, an examination of the structure of the model by considering formulations that have fewer, more or different explanatory variables, or a study of subgroups of observations, looking for those that are either poorly represented by the model (outliers) or that have a relatively large effect on the regression model's predictions.

Property Value
dbo:abstract
  • In der Statistik ist die Regressionsdiagnostik die Überprüfung, ob die klassischen Annahmen eines Regressionsmodells mit den vorliegenden Daten konsistent sind. Falls die Annahmen nicht zutreffen, sind die berechneten Standardfehler der Parameterschätzungen und p-Werte nicht korrekt. Die Problematik bei der Regressionsdiagnostik ist, dass sich die klassischen Annahmen nur auf die Störgrößen, nicht aber auf die Residuen beziehen. (de)

A regression diagnostic may take the form of a graphical result, informal quantitative results or a formal statistical hypothesis test, each of which provides guidance for further stages of a regression analysis.
