Biometrics concerns the study of automated methods for identifying an individual by measuring one or more physical or behavioral features.

In this non-technical talk, we discuss uncertainty – why it needs to be modelled – the role of probability theory, brief history of probability, and some of its popular applications.  We focus especially on modelling tail events - events that occu

Consider a sample of size $n$ from a linear process of dimension $p$ where $n, p \to \infty$,  $p/n \to y \in [0, \ \infty).$ Let $\hat{\Gamma}_{u}$ be the sample autocovariance of order $u$.
