Class comparing change in EMP under AIC from splitting 2 nodes. More...
Inheritance diagram for subpavings::CompEMPSumChangeAIC: Collaboration diagram for subpavings::CompEMPSumChangeAIC:Class comparing change in EMP under AIC from splitting 2 nodes.
Under AIC, EMP is -1 x sum over leaves of (counts in leaf x (ln(count in leaf /(n x vol of leaf))) where n is the total number of data points in the histogram
For two leaf nodes we are comparing the change in -1 x the sum over leaves of (counts in leaf x (ln(count in leaf /(n x vol of leaf) which would result if each node were to be the one to be split.
The smaller (more negative) the value returned by getSplitChangeEMPAIC(), the more a node will reduce or least increase the overall EMP by being split, so it should be higher, ie more to right, in the ordering.
