Query: Quantile Based Variable Mining : Detection, FDR based Extraction and
  Interpretation   This paper outlines a unified framework for high dimensional variable
selection for classification problems. Traditional approaches to finding
interesting variables mostly utilize only partial information through moments
(like mean difference). On the contrary, in this paper we address the question
of variable selection in full generality from a distributional point of view.
If a variable is not important for classification, then it will have similar
distributional aspect under different classes. This simple and straightforward
observation motivates us to quantify `How and Why' the distribution of a
variable changes over classes through CR-statistic. The second contribution of
our paper is to develop and investigate the FDR based thresholding technology
from a completely new point of view for adaptive thresholding, which leads to a
elegant algorithm called CDfdr. This paper attempts to show how all of these
problems of detection, extraction and interpretation for interesting variables
can be treated in a unified way under one broad general theme - comparison
analysis. It is proposed that a key to accomplishing this unification is to
think in terms of the quantile function and the comparison density. We
illustrate and demonstrate the power of our methodology using three real data
sets.
