“…The calibration of this model is studied in different ways: on marginal volatility and by maximum likelihood in [84,89], by the development of an efficient statistical estimation procedure on FPDs in [91], on implicit volatilities in [145], or by Markov chain Monte-Carlo method in [109]. Very recently, Fabbiani et al [86] calibrated the two-factor model on forward option prices in EEX markets by considering the model as the Schwartz and Smith [180] model. [149,94] have discussed the number of factors to be used to represent electricity prices in the FPDs in the Nord Pool market.…”
