WebWavelets are of wide potential use in statistical contexts. The basics of the discrete wavelet transform are reviewed using a filter notation that is useful subsequently in the paper. A ‘stationary wavelet transform’, where the coefficient sequences are not decimated at each stage, is described. WebI want to make a long forecast of it using wavelet transforms. By this moment I've made a fourier transform and got an expression for predicting the daily seasonality. So I've extracted frequencies and amplitudes for sine functions. Seasonal trend (orange) and reconstructed seasonal trend (blue) The blue curve is the sum of 5 sine functions ...
