- DataFrame.rolling(window, **kwargs)¶
Provides rolling transformations.
- Parameters
- windowint, str, offset
Size of the moving window. This is the number of observations used for calculating the statistic. When not using a

Minimum number of observations in window required to have a value (otherwise result is NA).
