%description
Given independent and identically distributed observations X(1), ...,
X(n), compute the maximum likelihood estimator (MLE) of a density as well
as a smoothed version of it under the assumption that the density is
log-concave, see Rufibach (2007) and Duembgen and Rufibach (2009). The
main function of the package is 'logConDens' that allows computation of
the log-concave MLE and its smoothed version. In addition, we provide
functions to compute (1) the value of the density and distribution
function estimates (MLE and smoothed) at a given point (2) the
characterizing functions of the estimator, (3) to sample from the
estimated distribution, (5) to compute a two-sample permutation test based
on log-concave densities, (6) the ROC curve based on log-concave estimates
within cases and controls, including confidence intervals for given values
of false positive fractions (7) computation of a confidence interval for
the value of the true density at a fixed point. Finally, three datasets
that have been used to illustrate log-concave density estimation are made
available.
