Envelope Models and Methods
R. Dennis
Friday, April 13, 2012 - 4:30pm

We will discuss a new approach to estimation in the classical multivariate linear model that yields estimators of the coefficient matrix with the potential to be substantially less variable asymptotically than the standard estimators. The new approach arises by recognizing that the response vector may contain information that is immaterial to the purpose of estimating the coefficients, but can still introduce substantial extraneous variation into estimation. This idea leads to a general construct -- an envelope -- for removing the immaterial information and effectively reducing the dimension of the parameter space. Emphasis will be placed on the fundamental concepts and their potential impact on data analysis. Recent work in the area will be described.
