Re: CATEGORICAL AUTOCORRELATION: RCT analysis with 4 groups
开云体育So, I have a network called campnet and an attribute dataset called campattr where the third column has 3 categories: ? ? ? ?????????????? 1 2 3 ???????????????G R C ???????????????e o o ???????????????n l m ???????????????d e b ???????????????e?? o ???????????????r???? ???????????????- - - ????1?? HOLLY? 1 1 1 ????2? BRAZEY? 1 1 1 ????3?? CAROL? 1 1 1 ????4???? PAM? 1 1 1 ????5???? PAT? 1 1 1 ????6? JENNIE? 1 1 1 ????7 PAULINE? 1 1 1 ????8???? ANN? 1 1 1 ????9 MICHAEL? 2 1 2 ???10???

When I run the RCT procedure I tell it that the attribute is “campattr col 3” and it gives the results below. I gather it’s not working that way for you. I’m guessing that your nodeattr dataset contains two columns of actual data (not one column plus row labels). If so, you should be telling it “nodeattr col 2” ? steve ?

2-Mode Core/Periphery Data

Re: MRQAP
Am humbled that you are one of the people responding to my question. Really humbled. To answer your query, data collection was done by asking on sharing of knowledge among people in a water service system. That is, questions were asked on who and who regards to types of relationships and interactions in the service system that necessitated sharing of beneficial knowledge for effective water supply.

Re: MRQAP
开云体育As in all regression, the r-square tells you how well you are predicting. In your case, it is exceptionally high, so you are predicting with near-perfect accuracy. That’s not always a good thing. It suggests that one or more of your independent variables are basically synonymous with your dependent variable. Is there anything artifactual in your data collection that might be causing this very high correlation? For example, it looks like the dependent variable is knowledge sharing. Did you perhaps only ask the sharing question about alters that the respondent had a relationship with? That would create a very high correlation between your X variables and your Y. ? steve ?

Re: Attribute transformation question
开云体育Narmin, your question isn’t specific enough to be answerable. But in case it helps, I would work with your attributes in excel, and then cut and paste them into spreadsheet editor or the dl editor in ucinet. ? steve ? From: ucinet@...

Flow Betweenness
Hello Everyone, I would like to ask about the Flow Betweenness calculation in Ucinet, it gives in its product two different versions of solutions, one is old and the other one is new starting from version 5.2.0.0. Could anyone explain what is the conceptual difference between them? Is there any chance that one of them is the Random Walk Betweenness? Thank you! Kind Regards, Robert |
