The array (random_walk == -10) is made up of booleans, so it will return the index of the first occurrence of -10 in each column.

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.
