ARIMA (0,1,0) is random walk. It is a cumulative sum of an i.i.d. process which itself is known as ARIMA (0,0,0). @g3o2, the real answer is in the first line. To make it artificially longer, I have added the second line. (OK, this is a joke. The second line gives the definition of a random walk.) douro wine cruise
