Exponential random graph coefficients of an elephant association network showing that the elephant network had a sparse density of associations, a strong clustering, a strong association by raiding status and a weak association by age (n = 58 elephants).

1Transitivity parameter indicates clustering and a schematic representation of this and other parameters in this table are shown in Figure S1.
2Data on age differences between dyads was used to test whether associations in the network are based on age proximity in this analysis.

1. 传递性参数（Transitivity parameter）用于表征网络的聚集特性，该参数及本表格中其余参数的示意图详见图S1。
2. 本分析中，我们采用成对个体间的年龄差数据，以检验网络中的关联是否基于年龄相近性。
