Hi,
I'm using py-earth with multicolumn input and multicolumn output. Currently I have the pruning pass enabled. I ran into this problem where sometimes the selected iteration doesn't appear to come out right. I understand that the selected iteration is the one with the minimum GCV among all iterations in the pruning pass? Sometimes the selected iteration comes out to be 0, resulting in a large model, even though that's not the iteration with the minimum GCV.
I ran some tests as shown below. It seems it might have to do with multicolumn output?
Thanks! Charles
