***** To join INSNA, visit http://www.insna.org ***** The help file states the following. A triple of three vertices x,y and z taken from a valued graph is weakly transitive if whenever there is a tie connecting x to y and y to z stronger than some fixed value s then there exists a tie connecting x and z greater than a smaller value w. This routine checks for weak transitivity by taking the largest value in the graph for s and a user prescribed value for w. The value of s is reduced until a triple is found that violates the weak transitivity condition. The value of s is then used to dichotomize the graph. The components (weak components for digraphs) of this dichotomized graph form the mutually exclusive F-groups. Borgatti, S.P., Everett, M.G. and Freeman, L.C. 2002. Ucinet 6 for Windows. Harvard: Analytic Technologies. hence the routine starts with the largest value this would be level 1. If there is no violation then it takes the next largest value this would be level 2 and so on until a triple is found that violates the condition. The value is therefore the one used to dichotomize the graph, the level is the order in which it appears if the values on the edges were placed in descending order.

I used the f groups function of UCINET to account the strengths of the ties into the analysis. However, I am not able to understand the output quite clearly. When I get the output as follows: Strong ties have value 12.00 (level 11). GROUPS WITH 2 OR MORE MEMBERS: What does that value mean and what does the level mean? What is the range of cut off value that goes as input? Thanks in advance.

I am usign UCINET for analyzing one of my social networks. I am focussing on the sub-group functionality of UCINET. Is there any function that considers the strength of ties between the nodes? Do let me know. Best Neha --------------------------------- Enjoy this Diwali with Y!
