--------------------------------------
Resolution: Later
Pushed this to "Later" - at least until we better sort out how to structure
ways to not pollute the core {{GraphTraversal}} space.
> Implement AssortativeMixingVertexProgram.

> Key: TINKERPOP-382
> URL: https://issues.apache.org/jira/browse/TINKERPOP-382
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.0.2-incubating
> Reporter: Marko A. Rodriguez
> Priority: Major
>
> This is a VertexProgram and a MapReduce job.
> . VertexProgram: for user stated property, send property value message to
> outgoing neighbors. Neighbors save their property value along with the
> property value of their neighbor in a {{List<Pair<Object,Object>>}}.
> . MapReduce: do a SpearmanRank, Pearson, or Kendall Tau correlation on the
> concatenated {{List<Pair<Object,Object>>}} from the VertexProgram -- emit a
> single {{Double}} (the correlation) in the {{generateFinalResult()}}.
