#' Sparse Matrix Estimation and Inference
#'
#' The \code{sparseMatEst} library provides functions for estimating
#' sparse covariance and precision matrices with error control.
#'
#' Given a data matrix, this package contains two main functions
#' used to estimate the covariance matrix and the precision matrix
#' of the data under the assumption of sparsity, that most
#' off-diagonal entries are zero. This is achieved by selecting
#' a false positive rate corresponding to the probability that
#' a true zero entry is falsely chosen to be non-zero by the estimator.
#'
#' The false positive rate can be treated as an interpretable
#' penalization parameter. Setting this to zero will return
#' a diagonal matrix. Choosing a false positive rate away from
#' zero will allow for the estimator to contain some non-zero
#' off-diagonal entries.
#'
#' Future updates coming Fall 2019 include inferential tools
#' based on these
#' sparse matrix estimators. These include a variant of
#' linear and quadratic discriminant analysis, fitting a
#' Gaussian mixture assuming sparsity, network clustering
#' algorithm, and a method to fit a random design linear
#' regression model.
