Hierarchical shrinkage
Web31 de ago. de 2013 · Here is an example. You can see the extent of the shrinkage by the the distance covered by the arrow towards the higher level estimate. Note the arrows do sometimes point away from the higher level estimate. This is because this data is for a single coefficient in a hierarchical regression model with multiple coefficients.
