COMPARING NUMERICAL METHODS OF THE EVANS PRICE ADJUSTMENT MODEL FOR GLOBAL SILVER PRICE

Abstract. This research paper centred on how the global silver price can be estimated and predicted by implementing Evans Price Adjustment model (EPA). Firstly, we derived equation that represent capture data involving price, demand, supply of 2013-2021. We deployed two different numerical methods solving ordinary differential (ODE). The first method is 4th order Adam Bashforth-Moulton second Euler method. Same problem were solved using methods, an attempt to check effectiveness methods. From there, able affirm more suitable technique for this problem. which based fundamental principle economics was chosen because it established a relationship between demand supply. used in work collected from World Bank, public open-source trustable website arbour regarding commodities. our findings, proclaimed successful, since results obtained follow trend real data. Although, ABM4 predictive outperformed its counterpart predicting accurately, but both approaches within time frame. Hopefully, would useful reference materials investors other shareholder business.
