“…The model minimized the prediction errors were based on MAPE of 1.902, RMSE of 0.080, and MAE of 0.054. Reference [21] discovered that the SARIMA (0, 1, 1) (0,1,1)4 model was the best fit for tomato prices in Ghana's Ashanti region (BIC = 5.969). They observed significant price fluctuations in tomato prices throughout the year.…”

“…The efficiency of ARIMA and GARCH models were compared for modelling and forecasting the spot prices of Grams in India [23] and the SARIMA models were used to forecast the prices of Tomatoes in selected Indian states [19]. Gathondu [11] fitted four models to wholesale prices of major vegetables: tomato, potato, cabbages, kales and onions for markets in Nairobi, Mombasa, Kisumu, Eldoret and Nakuru in kenya using Autoregressive Moving Average (ARMA), Vector Autoregressive (VAR), Generalized Autoregressive Condition Heterostadicity (GARCH) and the mixed model of ARMA and GARCH.…”

“…They reported that the highest tomatoe prices seasonally adjusted were in October. Boateng et al, [19] found that the predictability of the model increased with seasonal ARIMA (SARIMA). They noted wide fluctuations in prices of tomatoes in different months, prices sometimes increase 10 times compared to prices during peak harvest periods which implied that if farmers plan their area under tomatoes properly, sowing dates and sales by considering forecasted prices from the ARIMA models to receive increased prices, earnings may increase at least three to four times with 90% predictability of the forecast accuracy.…”

“…En ese contexto, la necesidad de pronosticar el valor futuro de productos perecederos de corta vida de almacenamiento, es un objetivo principal en numerosas investigaciones alrededor del mundo (Boateng et al, 2017;Dharavath y Khosla, 2019;Paredes-García et al, 2019;Weng et al, 2019;Sabu y Kumar, 2020).…”
