Abstract: spdir generates a directed dyad contagion spatial effect variable for analysis of spatial dependence in directed dyad data. It can create spatial effect variables for spatial lag, spatial-x and spatial error models. See http://personal.lse.ac.uk/neumayer/spatial.pdf for an explanation of what constitutes directed dyad contagion. Requires installation of the mmerge package (q.v.)
