摘要：Wavelets allow for a more flexible characterization of time series than both and classical time series methods, them with basis functions that between time and scale. In this paper, we briefly present the main definintions and results of both wavelet and wavlet packet analyzes and apply some of them to the Libson stock index (IBVL). We denoise the series, separate trend and Monte Carlo estimation of the fractal dimension of the series.
