“…The parametric approach includes the historical average (HA) method, autoregressive moving average method (ARIMA) [6,7], seasonal autoregressive integrated moving average method (SARIMA) [8][9][10], and Kalman filter (KF) [11,12]. The nonparametric approach includes artificial neural networks (ANNS) [13][14][15][16][17], k-nearest neighbor (KNN) [18][19][20][21][22], support vector regression (SVR) [23,24], and the Bayesian model [25,26]. The hybrid approach mainly combines the parametric approach with the nonparametric approach [27][28][29][30][31][32][33][34][35].…”
