Comparison of the predictions from the Holdout-data and Full-data models for the same 75% of the data split into spatially representative test and train samples using Generalized Random Tessellation Stratified (GRTS) with the associated r-squared value for each water quality variable. The 1:1 line is represented by a solid black line.
