Gaussian Random Walk with Drift¶. A Gaussian random walk with drift is the same as a random walk except at each time step the drift rate \(\mu\) is added to the path.; The setup is the same as above except you need to choose a drfit rate \(\mu\) and add this term into your for loop so that \(y_{t} = \mu + y_{t-1} + \epsilon_{t}\) For example, your code could look like this:

For an alternative formulation, you can take the cumulative sum of a constant mean white noise (WN) series, such that the mean corresponds to the slope of the RW time trend.

Many time series, like stock prices, are random walks but tend to drift up over time.
