%description
Providing six different algorithms that can be used to split the available
data into training, test and validation subsets with similar distribution
for hydrological model developments. The dataSplit() function will help
you divide the data according to specific requirements, and you can refer
to the par.default() function to set the parameters for data splitting.
The getAUC() function will help you measure the similarity of distribution
features between the data subsets. For more information about the data
splitting algorithms, please refer to: Chen et al. (2022)
