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!
I think Ljung's System Identification: Theory for the user is the authoritative reference, although it was a bit difficult for me.
I have found there are several "schools of thought" in the field that pervade theory, notation, and approach to essentially the same methods: control (ODEs), statistics (ARIMA methods), signal theory (Kalman filters)...
You can also differentiate between continuous/discrete time approaches. As far as I recall, Ljung's book was mainly discrete.
