Hi all, Can any body suggest me the data set which has the length of power of two and fit for the wavelet smoothing for the regression? There are alot of datasets like "ethanol" in the package "SemiPar" that can be used for this smoothing but we have to extend them in the power of two. I have no idea of this. If any body give the technique for this, it will be great. Best [[alternative HTML version deleted]]
