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…
