%description
A data augmentation based sampler for conducting privacy-aware Bayesian
inference. The dapper_sample() function takes an existing sampler as input
and automatically constructs a privacy-aware sampler. The process of
constructing a sampler is simplified through the specification of four
independent modules, allowing for easy comparison between different
privacy mechanisms by only swapping out the relevant modules. Probability
mass functions for the discrete Gaussian and discrete Laplacian are
provided to facilitate analyses dealing with privatized count data. The
output of dapper_sample() can be analyzed using many of the same tools
from the `rstan` ecosystem. For methodological details on the sampler see
Ju et al. (2022) <doi:10.48550/arXiv.2206.00710>, and for details on the
discrete Gaussian and discrete Laplacian distributions see Canonne et al.
(2020) <doi:10.48550/arXiv.2004.00010>.
