The frequency of hunter-gatherer movement is associated with implement diversity.


Variables proxying frequency of movement: number of annual residential moves (NMV), natural log of total annual migration (LDMV). Variables proxying implement diversity: total number of complex subsistants (CSTS), total number of complex subsistant types (NCT), total number of subsistants (STS). Out of four regression models run on each of the diversity variables (a total of twelve models), NMV is included in all of the models except the forward stepwise regression model against STS, and LDMV is in none of the models.
