Abstract :
This paper describes a systematic approach to the problem of estimating the spectrum of Lyapunov exponents in a consistent and robust way given a scalar time series as input. The spurious exponents which occur as a result of the embedding process can be removed by evaluating the tangent maps in local vector spaces calculated using singular value decomposition of the neighbourhood matrices
