Greeting.
Dimitirs and I are using the E-I index function of Ucinet to analyze a two
mode data about profs of computer science and electrical eng at UC Berkeley
and Stanford. We try to model relationship of co-foundation, advisory, and
board director of the companies in and around silicon valley.
For the concept E-I index, we referred Krackhardt, D and Stern, R N (1988)
Informal Networks and Organizational Crises, Social Psychology Quarterly,
51, 2, 123-140. (http://www.andrew.cmu.edu/user/krack/academic/papers.html)
and Valdis Krebs’ work of Post-Merger Integration
(http://www.orgnet.com/merger.html).
We met a technical problem in calculating the index with Ucinet. We made up
a small symmetrical binary dataset and a corresponding attribute dataset to
test the E-I Index function (network – network properties – E-I index).
However, after running the function, there is only a Log file, saying
‘Warning: This procedure ignores direction of ties’, and without the
expected output file IndE-I. We changed the inputs into different forms,
but got the same result.
Anybody who met this problem before?
The followings are the test datasets and Log file.
Input dataset:
A B C D E F
A 1 1 1
B 1 1 1 1 1
C 1 1 1
D 1 1 1 1
E 1 1
F 1 1 1 1 1
Attribute dataset:
A 1
B 1
C 1
D 2
E 2
F 2
OUTPUT.LOG1
E-I INDEX

Adjacency dataset: D:\Mes documents\UCinet test\test 1
Attribute: test 1 group col 1
# of Permutations: 5000
Random seed: 2923
Individual E-I scores: IndE-I
Warning: This procedure ignores direction of ties.
