We do not advise computing KGE or KGE' with log-transformation as it might be wrongly influenced by discharge values close to 0 or 1 and it is dependent on the discharge unit. See Santos et al. (in review) for more details and alternative solutions (see the reference below).
The epsilon value is useful when \code{"log"} or \code{"inv"} transformations are used (to avoid division by zero). The effect of this value and recommendation about the epsilon value to use (usually one hundredth of average Qobs) are discussed in Pushpalatha et al. (2012) for NSE and Santos et al. (2018) for KGE and KGE'. \cr
