What's the difference bewteen resubPredict and predict functions?

I'm trying to use Gaussian Process regression and came across two functions

'resubPredict' and 'Predict'

I've read the documentation regarding both functions but can't find the difference between these two.

Well is there any difference between these two?

Hi Jae,

The ‘resubPredict’ function is used to get predictions on the training data itself, while the ‘predict’ function is used to get predictions on new or unseen data. Therefore, the input requirements and output formats also differ between the two functions.
