Authors observed that there is a relationship between global prices of wheat and prices in Poland. The authors of this article have identified a process ARIMA (0, 1, 1) as a stochastic model to describe the global prices of wheat. They also found a correlation coefficients, which confirmed the relationship between the global and Polish prices.
