HPSPLIT - non negative predictions

skaminsk — Fri, 08 Oct 2021 16:05:13 GMT

In my original dataset, the response variable (RESIDUALS) can be less than zero. However, all the predictions (P_RESIDUALS in data_out) are non-negative. Where is the setting to allow negative predictions?

proc hpsplit data=data_in nodes;
class DIM1 DIM2;

model RESIDUALS = DIM1 DIM2;

grow RSS;
prune REDUCEDERROR(leaves=8);
output out=data_out;
id _Leaf_ DIM1 DIM2;
run;quit;

Try removing the Leaves= on the PRUNE setting or even test without pruning.

Just how common are your negative values? If they are uncommon I would suspect that you may need a fuller tree to get them.
