%description
Implementation of Stepwise Clustered Ensemble (SCE) and Stepwise Cluster
Analysis (SCA) for multivariate data analysis. The package provides
comprehensive tools for feature selection, model training, prediction, and
evaluation in hydrological and environmental modeling applications. Key
functionalities include recursive feature elimination (RFE), Wilks feature
importance analysis, model validation through out-of-bag (OOB) validation,
and ensemble prediction capabilities. The package supports both single and
multivariate response variables, making it suitable for complex
environmental modeling scenarios. For more details see Li et al. (2021)
<doi:10.5194/hess-25-4947-2021>.
