%description
Tuning-free kernel density estimation for heaped and rounded data using a
characteristic-function theory of heaping. Rounding to a grid is
convolution with a box followed by lattice sampling, so the density is
recovered by deconvolving the known box and tapering against a data-driven
noise floor. Provides a box-deconvolution de-heaping estimator, a
superposition variant, and a single combined estimator selected by a
band-capacity gate; grid, heaped-fraction, and mixed-grain readers; and a
spectral higher-order comb detector. Base-R replicas of the Heitjan-Rubin
multiple-imputation and measurement-error deconvolution methods are
included for comparison, and the 'Kernelheaping' stochastic
expectation-maximization estimator is used when installed.
