Figure 3.

Partially causal network inferred from the Arabidopsis thaliana data by the method introduced in this paper – note the difference to the correlation network of Figure 1. The topology of the partially causal network is identical to that of a partial correlation graph (GGM, CIG). However, edges with significant directionality (as indicated by a factor <a onClick="popup('','MathML',630,470);return false;" target="_blank" href="">View MathML</a> that is significantly smaller or larger than one) are oriented.
