Differentially private projection-depth-based medians
Kelly Ramsay, Dylan Spicker
We develop -differentially private projection-depth-based medians using the propose-test-release (PTR) and exponential mechanisms. Under general conditions on the input para…
Differentially private multivariate medians
Kelly Ramsay, Aukosh Jagannath, Shoja'eddin Chenouri
Statistical tools which satisfy rigorous privacy guarantees are necessary for modern data analysis. It is well-known that robustness against contamination is linked to differential…
Robust changepoint detection in the variability of multivariate functional data
Kelly Ramsay, Shoja'eddin Chenouri
We consider the problem of robustly detecting changepoints in the variability of a sequence of independent multivariate functions. We develop a novel changepoint procedure, called…
Robust nonparametric hypothesis tests for differences in the covariance structure of functional data
Kelly Ramsay, Shojaeddin Chenouri
We develop a group of robust, nonparametric hypothesis tests which detect differences between the covariance operators of several populations of functional data. These tests, calle…
Differentially private depth functions and their associated medians
Kelly Ramsay, Shoja'eddin Chenouri
In this paper, we investigate the differentially private estimation of data depth functions and their associated medians. We introduce several methods for privatizing depth values…
Robust multiple change-point detection for multivariate variability using data depth
Kelly Ramsay, Shoja'eddin Chenouri
In this paper, we introduce two robust, nonparametric methods for multiple change-point detection in the variability of a multivariate sequence of observations. We demonstrate that…
