address two specific questions: "Masked by stochasticity, do financial data exhibit deterministic nonlinearity?", and "If so … fixings, and the USD-JPY exchange rate. For each data set we apply surrogate data methods and nonlinearity tests to quantify … linear noise or conditional heteroskedastic models and that there therefore exists detectable deterministic nonlinearity that …
