Figure 3From: Partial correlation analysis indicates causal relationships between GC-content, exon density and recombination rate in the human genomeIllustration of the procedures in establishing undirected, directed, or partially directed graphs. (A) If correlation Cor(i, j) is significant, draw an edge between node i and node j (i, j ∈ (x, y, z)). (B) The conditional correlation Cor(x, y|z) is insignificant, remove the edge (x, y). (C) Using other information to select one or few causal models that are consistent with the data.Back to article page
