Detection of Change--Points in the Spectral Density. With Applications to ECG Data

arXiv:0901.2996

Abstract

We propose a new method for estimating the change-points of heart rate in the orthosympathetic and parasympathetic bands, based on the wavelet transform in the complex domain and the study of the change-points in the moments of the modulus of these wavelet transforms. We observe change-points in the distribution for both bands.
