Predictive regression allows forecasters to focus on the prediction of asset returns conditioned on a set of one-period lagged predictors.

I am Professor of Mathematics at the University of California, Irvine working in high-dimensional probability theory and its applications.

I study probabilistic structures that appear across mathematics and data sciences, in particular random matrix theory, geometric functional analysis, convex and discrete geometry, high-dimensional statistics, information theory, learning theory, signal.

Hill. Dec 19,  · Multivariate analysis is a mainstay of statistical tools in the analysis of biomedical data. It concerns with associating data matrices of n rows by p columns, with rows representing samples (or patients) and columns attributes of samples, to some response variables, e.g., patients outcome.

May 03,  · Large datasets, where the number of predictors p is larger than the sample sizes n, have become very popular in recent years.

These datasets pose great challenges for building a linear good prediction model. In addition, when dataset contains a fraction of outliers and other contaminations, linear regression becomes a difficult problem.
