All models are lies. "The Earth orbits the sun in an ellipse with the sun at one focus" is false, but accurate enough for almost all purposes. This book describes the current state of the art of telling useful lies about time-varying systems in the real world. Specifically, it is about trying to "understand" (that is, tell useful lies about) dynamical systems directly from observa- tions, either because they are too complex to model in the conventional way or because they are simply ill-understood. B(: cause it overlaps with conventional time-series analysis, building mod- els of nonlinear...
