(X_f, X_o, metric, **kwargs)¶ Compute mean ensemble skill for a given skill metric.
Parameters: - X_f : array-like
Array of shape (l,m,n) containing the forecast fields of shape (m,n) from l ensemble members.
- X_o : array_like
Array of shape (m,n) containing the observed field corresponding to the forecast.
- metric : str
The deterministic skill metric to be used (list available in
get_method()
).
Returns: - out : float
