Hello,
When using a GAM model from a training set to predict the test set containing,
I get the following warning message:
_________________________________________

Warning messages:
There is a 0% discrepancy between the original and the re-fit used to a
chieve 'safe' predictions in: safe.predict.gam(object, newdata, type, se.f
it, terms)

__________________________________________
I think I am using the correct syntax for predict.gam, and the columns in the
newdata correspond to the predictors that were used in the GAM model
for the training set. What does this warning message mean?
Thanks in advance for any help.
Devan
