Webb3 juni 2024 · A random walk model is : Yt = drift + Y (t-1) + shock. My idea which I now realize is missing in my loop, was to use that first value of rw1 and then have the rest of the vector be filled by that same model using the previous value in rw1. So it would have something like : ```rw [i] <- drift + rw [i-1] + shock ´´´ – Santiago Vallejo Webb14 dec. 2024 · In the streaming model, we show how to perform several graph computations including estimating the probability distribution after a random walk of …
