Orthogonal decompositions in growth curve models
Daniel Klein, Ivan Žežula · Acta et Commentationes Universitatis Tartuensis de Mathematica · 2010
The article shows advantage of orthogonal decompositions in the standard and extended growth curve models. Using this, distribution of estimators of ρ and σ2 in the standard GCM with uniform correlation structure is derived. Also, equivalence of Hu and von Rosen conditions in the extended GCM under mild conditions is shown.
