Obtain Trace of the Projection Matrix in a Linear Regression

October 6, 2011
By

Recently, I am working on coding in SAS for a set of regularized regressions and need to compute trace of the projection matrix: S=X(X'X + \lambda I)^{-1}X'. Trace of the project matrix S is a key concept in modern regression analysis. For example, ...
