#' SelectBoost
#'
#' Motivation: With the growth of big data, variable selection has become one of the major
#' challenges in statistics. Although many methods have been proposed in the literature their
#' performance in terms of recall and precision are limited in a context where the number of
#' variables by far exceeds the number of observations or in a high correlated setting.
#' Results: This package implements a new general algorithm which improves the precision of any
#' existing variable selection method. This algorithm is based on highly intensive simulations and
#' takes into account the correlation structure of the data. Our algorithm can either produce a
#' confidence index for variable selection or it can be used in an experimental design planning
#' perspective.
