Type 1 error rates using all pathway information, i.e., no nodes or edges were dropped for these simulations.

“Perfect” indicates calculating from the graph used to generate the data. “Mismatch” indicates the percentage of direct edges that were incorrect. Error rates were calculated from score tests on 1000 simulated data sets. All simulations used graphs with 15, 30, or 45 nodes. “Complete Mismatch” indicates 100% mismatch.
