Pandas Rolling Computations on Sliding Windows (Unevenly spaced)

Question

Consider you\'ve got some unevenly time series data:

import pandas as pd
import random as randy
ts = pd.Series(range(1000),index=randy.sample(pd.date_range(\         


        

Answer 1

Perhaps it makes more sense to use rolling_sum:

pd.rolling_sum(ts, window=1, freq='1ms')
