Non-linear Time Series Analysis

  • Bruce Mizrach
Reference work entry


Since the early 1980s, there has been a growing interest in stochastic nonlinear dynamical systems of the form xt+1 = f (xt, xt−1, …, xtp) + σ(xt)εt, where \( {\left\{{x}_t\right\}}_{t=0}^{\infty } \) is a zero mean, covariance stationary process, f : Rp+1R, σ is the conditional volatility, and \( {\left\{{\varepsilon}_t\right\}}_{t=0}^{\infty } \) is an independent and identically distributed noise process. The major recent developments in nonlinear time series are described using this canonical model: (a) representation theory; (b) nonparametric modelling; (c) ergodic properties; (d) piecewise linear models; (e) volatility modelling; (f) hypothesis testing for linearity and normality; (g) forecasting.
