Re: About two-mode analysis on xUCINET and UCINET
Hi I vaguely recall an error in the Davis data that was corrected and this could cause the change. Also we do update and improve routines and correct bugs and these too could make a difference. Martin

Re: About two-mode analysis on xUCINET and UCINET
Hi Martin, Thanks! That¡¯s really helpful. I tried the dual-projection method, following the steps mentioned in the document. There are indeed 5 core events now. But the women-by-women partition

Re: About two-mode analysis on xUCINET and UCINET
Hi Dual core periphery in UCINET uses the categorical method whereas xUCINET uses the dual projection which is a continuous method. The later and usually better method is the dual projection. This can

About two-mode analysis on xUCINET and UCINET
Dear all, I¡¯ve used UCINET to run Davis_SouthernWomen data, using 2-mode categorical core-periphery. As the attached output shows, the core events are 7, 8, and 9. But these results seem different

Re: Finding Network Motifs
Sure. Suppose I construct the woman-woman 1-mode projection from the davis data, accepting the default output name of davisrows. Now, I run network|subgroup|fgroups on davisrows:

Re: xUCINET installation
Hi, there is a bug. You can fix the problem by installing the "blockmodeling" package before installing the xUCINET package. In R Studio, use the install.packages function as follows: Then following

Dear all, I¡¯ve tried to install xUCINET on RStudio, but failed. I followed the steps as suggested here: https://www.analyzingsocialnetworksusingr.com/xucinet. The error message is: ERROR: dependency

Re: Finding Network Motifs
Is there a way to also dichotomize in UCINET via g-transitivity?
By Scott Thomas · #6851 ·
Re: Finding Network Motifs
So far dichotomizing and exporting has worked fine, at least for 115 and 133 symmetric datasets I've tried and that includes success with finding triads and tetrads although that will take some time

Re: Finding Network Motifs
Comparing my Bonich'72 starting data with the above I can see only one difference. My data has three digits past the decimal and your data is rounded to off to two digits past the decimal. Could that

Re: Finding Network Motifs
Actually, I think I might have mixed up the cutoff with the correlation. But, btw, the numbers you are showing look slightly different from mine. A problem with the sorting? steve

Re: Finding Network Motifs
1. I cannot still am not sure about the 0.816 value and although that is a good correlation, there are higher values. 2. Thank you Nelson, but I do not do network analysis on a consistent basis every

Re: Finding Network Motifs
Hi Scott, I use UCINet for many network analysis, but for motif counting, characterizing and modelling I prefer working in R (i.e., igraph). Best of luck. Nelson Jatel, Doctoral Candidate Nelson R.

Re: Finding Network Motifs
Thank you. Actually this approach to dichotomizing is forcing me to reassess my method which was assigning 1 to mean +/- 1SD and all else a zero with the recognition that low degree individuals are

Re: Finding Network Motifs
I followed the procedure described at the bottom of page 5 in this paper: https://uknowledge.uky.edu/management_facpub/5/ The technique is implemented in ucinet's 'Transform|Dichotomize interactively'

Re: Finding Network Motifs
Ok. Looks good, but only one question. Why choose 0.816 as the dichotomize value? Wouldn't 0.50 be acceptable or perhaps the mean value of the matrix?

Re: Finding Network Motifs
This software could be very useful. Thanks for bringing it to our attention. An advantage of the UCINET data export is that you can vary the minimum tie value to focus on the more strongly connected

Re: Finding Network Motifs
Scott, your mfinder program wants non-valued data (it's trying to count up things like triadic configurations). So, you would need to dichotomize your valued 1-mode data. For example, suppose I have
