WebRolling Statistics This is the rolling average of the mean and standard deviation of a time series. Here rolling average differs from the way general average in that it will replace a data point with the average of its previous n data points. Here n is defined as the count of previous data points i.e. 10 days. Rolling means creating a rolling window with a specified size and perform calculations on the data in this window which, of course, rolls through the data. The figure below explains the concept of rolling. It is worth noting that the calculation starts when the whole window is in the data.
