nctoolkit.DataSet.rolling_var

DataSet.rolling_var(self, window=None, align='right')

Calculate a rolling variance based on a window

Parameters

• window (int) – The size of the window for the calculation of the rolling sum

• align (str) – This determines whether the output time is at the left, centre or right hand side of the time window. Options are “left”, “centre” and “right”

Examples

If you wanted to calculate a rolling variance with the variance calculated over every 10 time steps, do the following:

>>> ds.rolling_sum(10)
