- hydromt.stats.skills.lognashsutcliffe(sim, obs, epsilon=1e-06, dim='time')[source]#
Return the log Nash-Sutcliffe model efficiency.
Efficiency calculation is based on simulated and observed time series.
\[\begin{split}NSE = 1-\\frac{\\sum_{i=1}^{N}(log(sim_{i})-log(obs_{i}))^2} {\\sum_{i=1}^{N}(log(sim_{i})-log(\\bar{obs})^2}-1)*-1\end{split}\]- Parameters:
- Returns:
the log of the Nash-Sutcliffe model efficiency
- Return type:
