PDF Wavelet Analysis of Discrete Time Series - One scientic area where wavelet methods have been nding many applications is that of the analysis of discrete time series. A time series is dened to be a sequence of observations associated with an ordered independent variable t. Here we only consider the case of discrete values of

outliers - Application of wavelets to time-series-based - Wavelets are often compared to a continuous-time fourier transform, although they have the benefit of being localized in both time and frequency. An excellent reference work for discrete wavelets is Percival and Walden, "Wavelet Methods for Time Series Analysis"

Time series - Wikipedia - In mathematics, a time series is a series of data points indexed (or listed or graphed) in time order. Most commonly, a time series is a sequence taken at successive equally spaced points in time. Thus it is a sequence of discrete-time data
