Restrictions and Generalized Inverses in Linear Models

Pages 53-54 | Received 01 Dec 1982, Published online: 26 Mar 2012
 

Abstract

Given any generalized inverse (X'X) appropriate to normal equations X'Xb 0 = X'y for the linear model y = Xb + e, a procedure is given for obtaining from it a generalized inverse appropriate to a restricted model having restrictions P'b = 0 for P'b nonestimable.
