[PDP-discuss] Higher error in test than train?

[Randall C. O'Reilly]

this shouldn't happen, and so very likely reflects some kind of 
misconfiguration -- you are using different processes for train and test and 
there are various parameters in the trial and settle proc that you should 
double-check -- did you implement that different error stat?  copy it to both 
places?
