Dear all,
I now have the pairwise data in hand. I wonder how can I transform it into a matrix?
For instance, please see below the sample data. Now I have 8 pairs of inventors in the dta. In total, that involves 11 unique inventors.
And what I want to achieve is to transform it into a 11*11 symmetric matrix, in which 1 represents there is a link between two inventors (i.e., shown by the pairwise relationship), and 0 represents no such link exists.
Thanks in advance!
