[Rsiena-help] A question of Interpretation

[Nathan Doogan]

A negative coefficient would indicate a tendancy away from reciprocity while a zero coefficient would indicate actors are indifferent to reciprocal ties. Further, a zero coefficient does not mean reciprocity does not occur, but that it only occurs by random chance.
