We present a toolbox to compute and extract information from inhomogeneous (i. e. unequally spaced) time series.The toolbox contains a large set of operators, mapping from the space of inhomogeneous time series to itself. These operators are computationally efficient (time and memory-wise) and...

Most financial markets produce inhomogeneous (i.e. unequally spaced) tick-by-tick data at high frequency. Recently developed time series operators can be used to directly compute statistical variables such as volatility from inhomogeneous data. This is not possible with traditional time series...
