Nonparametric Neural Network Estimation of Lyapunov Exponents and a Direct Test for Chaos
(Vanderbilt University, 2003)
This paper derives the asymptotic distribution of the nonparametric neural network estimator of the Lyapunov exponent in a noisy system. Positivity of the Lyapunov exponent is an operational definition of chaos. We introduce ...
Is There Chaos in the World Economy?A Nonparametric Test Using Consistent Standard Errors
(Vanderbilt University, 2001)
A positive Lyapunov exponent is one practical definition of chaos. We develop a formal test for chaos in a noisy system based on the consistent standard errors of the nonparametric Lyapunov exponent estimators. When our ...
