When using SPSSINC TRANS, you have a wider array of functions to compute on cases in SPSS. Within the local session, you can create your own python functions within a BEGIN PROGRAM and END PROGRAM block. In SPSSINC TRANS you pass in the values in the current dataset, but you can also create...
This is a task I've have to conduct under several guises in the past. Given a set of edges, reduce those edges into unique subgroups based on the transitive closure of those edges. That is, find a group in which all nodes can reach one another (via however many steps are necessary) but are...
