Web$\begingroup$ @javlacalle May i ask that when you say it is correct, it is regarding my interpretation with respect to the equation that i wrote, because i think i might have the wrong equation interpretation in the place (due to the differencing) :/ I will share some of my finding below $\endgroup$ – misosoup WebJul 22, 2024 · As to the difference between your models with a deterministic & stochastic trend, we need to take a step back: You don't difference data if you expect a deterministic trend. So if you assume a data generating process y_t = c + beta * t + ARMA (p,q) (i.e. an ARMA process with a deterministic trend) you would not difference data.
