Krippendorff introduces social scientists to info idea and explains its software for structural modeling. He discusses key issues resembling: easy methods to ascertain a data conception version; its use in exploratory study; and the way it compares with different methods similar to community research, course research, chi sq. and research of variance.

Let the sequence of graphs resulting from the eliminations be G = GO,G1, G 2 , .. , G1 = G'. Assume that there exists a path connecting a and b through Y : a, yl', Y,', . . ,Y;, b. This is a path in GO. Let G i be the last graph in which this path is preserved. In the transformation from Gi to Gi+l, one vertex y' is eliminated and an edge is put between the adjacent vertices on the path, on both sides of y ' . Thus, in Gi++'there is still a path from a to b. This property is preserved after each elimination.
