WebAbstract. We introduce and study two new inferential challenges associated with the sequential detection of change in a high-dimensional mean vector. First, we seek a confidence interval for the changepoint, and second, we estimate the set of indices of coordinates in which the mean changes.

Web4. feb 2024 · In this paper, we propose a data-driven portfolio framework based on two regularization methods, glasso and tlasso, that provide sparse estimates of the precision matrix by penalizing its L_1 -norm. Glasso and tlasso rely on asset returns Gaussianity or t-Student assumptions, respectively.
