Fig 7. Gridge regression error compared to plain ridge, 5th season.

Gridge algorithms that take into account deceptiveness usually have lower RMSE than plain ridge, which does not. Further, adding deceptiveness noise usually gives the appropriate trend: worse deceptiveness knowledge means worse predictions. r² and RMSE on the 4th season show similar trends, while hit rate shows limited benefit from gridge; these figures are available in S1 Fig.
