Preprint: Wavelet transformations as diversity enhancers

Discussion Paper on Thresholding

Short abstract:
Discrete wavelet transformations have became indispensable
analytical tools in data compression and data denoising.
In this paper we give some
empirical accounts of wavelet transformations and
propose novel thresholding and wavelet selection methods.
This is achieved via connections with {it measures of inequality,}
that have been used in economics for a long time.
We compare our methods with standard
thresholding and wavelet selection procedures.

Comments, suggestions, and critiques welcome.
