Graphical Gaussian models with symmetries
- Abstract:
-
This thesis is concerned with graphical Gaussian models with equality constraints on the concentration or partial correlation matrix introduced by Højsgaard and Lauritzen (2008) as RCON and RCOR models. The models can be represented by vertex and edge coloured graphs G = (V,ε), where parameters associated with equally coloured vertices or edges are restricted to being identical.
In the first part of this thesis we study the problem of estimability of a non-zero model mean μ if the co...
