*The mean number of rooms inhabited at each site during each period [from (49)]. †Throughout this paper, the data for these periods are averages of results for two periods encompassing 1400–1450 CE and 1600–1650 CE, respectively, in (49).

‡Linear fit: 〈 ln [Nt]〉 = (0.006 ± 0.0007)t − (6.958 ± 0.9633), analysis of variance (ANOVA) F(1,8) = 108.8, P < 0.0001, r2 = 0.923.

§For three chronological groups of log-transformed observations (pre-1280, 1280–1450, and 1450–1650 CE), ANOVA F(2,193) = 13.995, P < 0.0001.

ǁFor three chronological groups of log-transformed observations (pre-1280, 1280–1450, and 1450–1650 CE), ANOVA F(2,148) = 11.162, P < 0.0001.
