AR dataset: an analysis based on robust dynamic linking and brushing

This movie shows how masking effects can be easily detectd by looking at forward plots. The movie also presents the effect of the outliers on the significance of one variable throught the so called added variable plot with the regression line coming from the addition of that variable when the potential outliers are included or excluded. The dataset was introduced by Atkinson and Riani in 2000. It contains 60 observations on a response with the values of three explanatory variables.

To find out more about this dataset please see Chapter 2 of "Robust Diagnostic Regression Analysis"
