pharmaco epidemiology Lars Småbrekke Department of Pharmacy UiT The Arctic University of Norway Why bother with Directed Acyclic Graphs DAGs Our problem Observational data and experimental data are different. In this note we give a similar result for the diameter of strongly connected directed graphs namely 2max log1 57374 log 1 where is the 57356rst nontrivial eigenvalue of the Laplacian and is the Perron vector of the transition probability matrix of We call the tail of the head of and uv the ends of If there is an edge with tail and head then we let uv denote such an edge and we say that this edge is directed from to Loops Parallel Edges and Simple Digraphs An edge uv in a digraph is a Data Structures & Algorithms.
