Dr. James McCaffrey from Microsoft Research presents a complete end-to-end demonstration of linear regression with two-way interactions between predictor variables. Compared to standard linear ...

A problem that can occur in a variance component analysis is the estimation and construction of confidence intervals for linear combinations of the variance components. This article considers the ...

Let MI denote the set of all scalar multiples of all isometries in a Hubert space H. In this paper finitedimensional linear spaces contained in MI will be investigated. Commutativity of such spaces ...
