Please I need a guide on how to compute Nash-Sutcliffe Efficiency (NSE) and Relative Error (RE) for model validation. These measures are novel to my study.
Please, an example would be excellent to guide me in my study.
Many thanks for your assistance.
Sometimes Google needs goggles, which is what rseek provides. Search for Nash-Sutcliffe Efficiency and you'll find a wealth of resources. Come on back when you have specific coding questions. (And add a reproducible example, called a reprex for a turbo-boost.
