%description
An implementation of common statistical analysis and models with
differential privacy (Dwork et al., 2006a) <doi:10.1007/11681878_14>
guarantees. The package contains, for example, functions providing
differentially private computations of mean, variance, median, histograms,
and contingency tables. It also implements some statistical models and
machine learning algorithms such as linear regression (Kifer et al., 2012)
<https://proceedings.mlr.press/v23/kifer12.html> and SVM (Chaudhuri et
al., 2011) <https://jmlr.org/papers/v12/chaudhuri11a.html>. In addition,
it implements some popular randomization mechanisms, including the Laplace
mechanism (Dwork et al., 2006a) <doi:10.1007/11681878_14>, Gaussian
mechanism (Dwork et al., 2006b) <doi:10.1007/11761679_29>, analytic
Gaussian mechanism (Balle & Wang, 2018)
<https://proceedings.mlr.press/v80/balle18a.html>, and exponential
mechanism (McSherry & Talwar, 2007) <doi:10.1109/FOCS.2007.66>.
