WebA random walk is a time series model x t such that x t = x t − 1 + w t, where w t is a discrete white noise series. Recall above that we defined the backward shift operator B. We can apply the BSO to the random walk: x t = B x t + w t = x t − 1 + w t. And stepping back further: x t − 1 = B x t − 1 + w t − 1 = x t − 2 + w t − 1. buy books or borrow booksWeb0. If an in nite number of equalizations occur, then the walk is called recurrent. If only a nite number of equalizations occur, then the walk is called transient.
