Let A be an abelian group with identity element 0. A graph G = (V,E) is said to admit an a-sum A-magic labeling if there exists an edge labeling ℓ : E(G) −→ A \ {0} and a ∈ A such that the induced vertex labeling ℓ+ : V (G) −→ A de_ned by is the constant map, ℓ+(u) = a for all...

To study the relationship between the linear statistical models we used methods of linear algebra, Hilbert spaces and statistics. It was found that there is a linear relationship between linear statistical models which is expressed by a matrix equality. Several corollaries are de...
