Re: 3-mode network
Thanks.? I¡¯m using 40 years of historic meeting minute records of watershed management in the Okanagan.? I would like to set-up a 3-mode network with the following three categories of nodes: - meeting date - organizations present - attendees present I¡¯ve set-up a 2-mode network with meeting dates and organizations and project to one mode easily enough.? I whould like to add the individuals attending each meeting, linked to the organizations so that I could project a 1-mode actor relationship too. Thoughts??

Average permutation frequency table - standard deviations
When using the Relational Contingency Table analysis (Tools->Testing Hypothesis -> Mixed Dyadic/Nodal -> Categorical Attributes -> Relational Contingency Table analysis) is it possible to get the standard deviations (or just the values from each iteration) associated with the Average permutation frequency table? Thanks. |

Re: Testing differences in average geodesic distances
¿ªÔÆÌåÓýThe density of a network is just the average value of the adjacency matrix that represents it. So you can run UCINET¡¯s compare densities command on any matrices, including geodesic distances, and it will compare their averages. ? steve ? From: ucinet@...

Combining a one- and two-mode dataset in Netdraw

¿ªÔÆÌåÓýHello Everyone, ? I am working with a student who has collected data regarding:

NETDraw INdegree Centrality
Hi Folks? I'm currently doing a dissertation investigating shared leadership in sports teams through social network analysis. I'm trying to use UCINet Netdraw to construct networks highlighting the leadership present within the teams. Basically my main query concerns the positioning of nodes within my network. I want to ensure that the nodes that are located most central in the network are those nodes with the highest indegree centrality. I cannot seem to figure out how to do this. I have managed to make the node size be determined by the indegree centrality but I have been unable to layout the network so those same nodes are in the middle are the nodes with a lower indegree centrality score are on the periphery of the network. If you would be able to help me with this query it would be greatly appreciated. Kindest regards, G |

Re: How many relations can Ucinet process?
¿ªÔÆÌåÓýOriana, you have a 2-mode matrix of 3500 rows (farmers) and 80 columns (technologies). You are considering converting to a 1-mode matrix of 3500 by 3500 farmers, where x(k,j) indicates the extent to which farmersws k and? j use the same technologies. There is nothing wrong with this, it makes perfect sense. ? You also wondered whether your 1-mode matrix of 3500 x 3500 farmers would be too big for ucinet. I tested this question by constructing a matrix of 3500 x 3500 and running several analyses. They all ran fine, so my conclusion was that you can do the analysis that you want in ucinet. ? Now, I did express some concern about visualizing the dataset. If it is very dense, it could be a lot of netdraw to handle. However, few minutes ago I just drew a network of more than 4000 nodes with high density, and it worked fine. So that may not be a problem either. ? steve ? From: ucinet@... <ucinet@...>

Re: Interpretation coefficients MR-QAP vs LR-QAP [2 Attachments]

Re: Interpretation coefficients MR-QAP vs LR-QAP [2 Attachments]
Dear Joshua, Obviously, the differences are between logit and multiple regression coefficients. If your question is about that difference please look it up on Google or Bing. Assuming you know that difference, there is little we can say about the parameters in your MR-model, let alone compare them with those in the LR-model. Unfortunately, the scale you produced for the dependent variable in the MR-model is nominal and maybe inconsistent. Its says something about perceived joint occurrence of events (sharing information in a specific situations), nothing about the frequency or amount of knowledge sharing. However, it isn't obvious that sharing information in any combination of two or three situations warrants the same codification (2 and 3, respectively). Why would sharing information during lectures and lunch, be the same as sharing information during lunch and outside campus? More generally, your questions differ in focus, some are more time-dependent (e.g. lunch), others are more dependent on place (e.g., off-campus). Adding them may not be such a good idea. The fact that you found significant results is a secondary result that only becomes of interest when you can interpret the parameters. Yet it seems you have some nice data. You collected data on 4 networks, where the relationship is about context of information sharing. Perhaps there is some theoretical argument or interest to assess whether three of these? networks affect a fourth? In choosing your model (MR vs. LR) I would not disregard the possibility of using MRQAP on a binary dependent variable. The linear probability model (that is what a MR-model is called when it has a binary dependent) certainly has its limits, but may be valid, for example, when heteroskedasticity consistent estimators are used. In fact, there are conceivable conditions where it may be a better solution than LRQAP, or even ERGM's. Best regards, David

Interpretation coefficients MR-QAP vs LR-QAP
Dear all, recently I collected a network dataset of 112 students and asked them, with whom
they share knowledge in 4 different occasions (e.g. having lunch,
outside the campus, in a lecture ...). So "knowledge sharing" would be my dependent
variable. If a student has chosen a person on all four occasions, he
will receive the value 4, so my matix has values between 0 and 4. My
independet variables are -- let?s say -- "same gender" and "same study
group". Is it better to dichotomize the dependent variable ("knowledge
sharing") to run a LR-QAP or should I leave the original 0-4-valued
coding and run a MR-QAP? The significances are similar, the coefficients
(odd ration etc.) of course not. It would be great if someone could
explain the differences in the interpretation of the coefficients (2.295 vs. 0.44).? Many thanks! Joshua LR-QAP (dichotomized the dependent var) MR-QAP (valued dependent var) |
