***** To join INSNA, visit http://www.sfu.ca/~insna/ ***** I am looking for an algorithm that has been coded in C++ or another language to calculate two measures of ego density for large matrices (500 x 500). The two measures are: 1) "traditional" measure: ties present / ties possible 2) Scott's (1991) measure: fraction of possible ties present among ego’s alters (i.e., this measure does not count ego's direct ties) Both measures should be able to account for dichotomous or weighted ties. I looked at Carter Butts' collection of S routines, but did not see an ego density algorithm. Any help would be greatly appreciated.
