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

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/216677We 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.proceeding of the workshop 'Fouille de données temporelles et analyse de flux de données' EGC'2009, january 27, Strasbourg, FranceMethodologyDetection of Change--Points in the Spectral Density.
