Continuous-Time Linear Models (Foundations and Trends(r) in Finance)

Discrete-time linear ARMA processes and lag operator notation are convenient for lots of calculations. Continuous-time representations often simplify economic models, and can handle interesting nonlinearities as well. But standard treatments of continuous-time processes typically don't mention how to adapt the discrete-time linear model concepts and lag operator methods to continuous time. Continuous-Time Linear Models attempts that translation and exposits the techniques to make the translation from familiar discrete-time ideas. The concluding section of this monograph collects the important formulas in one place. The author assumes a basic knowledge of discrete-time time-series representation methods and continuous-time representations.
