Hellow!

Actually, I want to delineate the groundwater potential zone by using the FR model.

But I am confused about groundwater well data that is used for in different research purposes. Most of the paper divides the data into two sets (training and testing) for validation and FR calculation. But, for my study area, that falls into only 19 wells. So i am confused that, can i divided it training and testing datasets or 19 well used for both validation and FR calculation?

Please suggest me.

Thanks in advance.
