Professionally I am analysing high-frequency data coming from motion sensors and alike. I would like to "up my theoretical background game" in this area and am therefore looking for recommendations to books about (I guess) statistics and probability theory concerning time series pehomena.
Concerning my background: I hold a master's degree in theoretical mathematics (Did some Probability Theory, statistics und stochastical analysis, though it was not my focus)
Any hints would be greatly appreciated. Thanks in advance!
