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

This movie shows that linking different forward plots can help in finding unexpected patterns in real complex data. The example shows the the first 54 observations coming from the first hospital cannot be considered homogeneous with respect to the last 54 observations coming from the second hospital.

To find out more about this dataset please see Riani and Atkinson (2007): Fast calibrations of the forward search for testing multiple outliers in regression. ADVANCES IN DATA ANALYSIS AND CLASSIFICATION. vol. 1, pp. 123-141 .
