Extended Data Table 6 Results for linear mixed model assessing whether calls addressed to a receiver imitate the receiver’s calls

From: African elephants address one another with individually specific name-like calls

  1. Each observation was a pair of calls and the response variable was rank-transformed proximity score. Imitation Pair Type = whether the receiver of one call in a pair was the caller of the other call (reference level = yes); Same Relationship = whether the callers of both calls in a pair had the same type of relationship to their respective receivers (reference level = no); Caller Dyad ID = unique combination of callers (random effect). Same Context, Same Date, and Pair ID same as in Extended Data Table 4. Pairs of calls recorded from different groups, pairs with the same caller or receiver, levels of Caller Dyad ID that only occurred with one level of Imitation Pair Type, and levels of Pair ID that only occurred once were excluded (n = 943 call pairs where receiver of one call was the caller of the other, 1553 where this was not the case). P-values are two-tailed.
