Data streams (streaming data) consist of transiently observed, evolving in time, multidimensional data sequences that challenge our computational and/or inferential capabilities. In this paper we propose user friendly approaches for robust monitoring of selected properties of unconditional and...

We introduce an empirical depth function for multivariate data based on the empirical likelihood ratio for the mean. This empirical depth function is defined through the empirical distribution of a sample. It is centred on the sample mean and has continuous, smooth and convex contours which...
