The forecast accuracy of the model. linear regression and std #211 - Backtrader Community Window Rolling Sum As a final example, let's calculate the rolling sum for the "Volume" column. Time series is any data which is associated with time (daily, hourly, monthly etc). import pandas as pd import numpy as np # Generate some random data df = pd.DataFrame (np.random.randn (100)) # Calculate expanding standard deviation exp_std = pd.expanding_std (df, min_periods=2) # Print results print exp_std. Working with Pandas dataframes with IBM TM1 and ... - Cubewise CODE 1 The output I get from rolling.std () tracks the stock day by day and is obviously not rolling. 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.
