Hypothesis
Political centralization will be predicted by population density, frequency of being attacked, and trade in the worldwide sample, but not in the Africa sub-sample.
Note
Authors created an interaction term between an Africa indicator variable and population density, frequency of being attacked, and trade. Being attacked and trade in the Africa sample had no significance, even though significant in the worldwide sample. Population density in Africa resulted in a significant relationship, however, trending in the opposite direction (b= -0.32; p<.01) compared with the whole sample (b= 0.36-0.38; p<.01).
