Wavelet Shrinkage,l shrinkage estimators for the location parameters. Some references are Donoho and Johnstone (1994), Donoho et al. (1995), Vidakovic (1999), Antoniadis et al. (2001), Pinheiro and Vidakovic (1997). In this chapter we focus on the simplest, yet most important shrinkage strategy—wavelet thresholding.

,Wavelet-Based Andrews’ Plots, subspaces are spanned by vectors whose coordinates are orthogonal trigonometric functions and this representation forms a Fourier expansion with coefficients being the coordinates of the data. Thus, every multivariate datum corresponds to a function, called Andrews’ curve.
