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


Variables proxying frequency of movement: number of annual residential moves (NMV), natural log of total annual migration (LDMV). Variables proxying implement elaborateness: total number of technounits (TTS), average number of technounits per subsistant (TTS/STS), total number of technounits summed over the most complex implement per implement type (MXT), average number of complex technounits per complex subsistant (CTTS/CSTS). Out of four regression models run on each elaborateness variable (for a total of sixteen models), NMV is included in all of the models except for the forward and backward stepwise regressions against TTS/STS and all of the models against CTTS/CSTS. However, LDMV is included in the two models against TTS/STS that NMV wasn't, and the authors discredited CTTS/CSTS as a response variable.
