The width of the line indicates the relative strength between two nodes.</P> <P>Hope that helps,</P> <P>Wendy</P> Tue, 10 Jan 2017 00:36:04 GMT https://communities.sas.com/t5/SAS-Data-Science/Link-Analysis-in-SAS-Enterprise-Miner-Interpreting-Results/m-p/323492#M4872 WendyCzika 2017-01-10T00:36:04Z https://communities.sas.com/t5/SAS-Data-Science/Link-Analysis-in-SAS-Enterprise-Miner-Interpreting-Results/m-p/323557#M4874 <P>Thanks Wendy - much appreciated!</P> Tue, 10 Jan 2017 10:02:16 GMT https://communities.sas.com/t5/SAS-Data-Science/Link-Analysis-in-SAS-Enterprise-Miner-Interpreting-Results/m-p/323557#M4874 HoaTruong 2017-01-10T10:02:16Z
