Model selection results for fitting probability distributions to carnivore litter size frequencies.

The number of datasets tested for each species (denominator, see Table S1 for details) and the number of datasets that were adequately fitted by a given distribution (numerator, see Table S2 for details). Bold indicates distributions that were most parsimonious for at least one dataset. SP: Shifted Poisson; ZTP: Zero-truncated Poisson; SB: Shifted binomial; ZTB: Zero-truncated binomial; SNB: Shifted negative binomial; ZTNB: Zero-truncated negative binomial; SGP: Shifted generalised Poisson; ZTGP: Zero-truncated generalised Poisson; DN: Discretised normal; DLN: Discretised lognormal; DSB3; Discretised stretched-beta (3 parameter form); DSB2; Discretised stretched-beta (2 parameter form).

针对各物种完成测试的数据集总规模（即分母，详细信息参见表S1），以及通过指定分布实现充分拟合的数据集数量（即分子，详细信息参见表S2）。标粗字体标记的为至少在一个数据集上表现为最简约的分布。SP：移位泊松分布（Shifted Poisson）；ZTP：截零泊松分布（Zero-truncated Poisson）；SB：移位二项分布（Shifted binomial）；ZTB：截零二项分布（Zero-truncated binomial）；SNB：移位负二项分布（Shifted negative binomial）；ZTNB：截零负二项分布（Zero-truncated negative binomial）；SGP：移位广义泊松分布（Shifted generalised Poisson）；ZTGP：截零广义泊松分布（Zero-truncated generalised Poisson）；DN：离散化正态分布（Discretised normal）；DLN：离散化对数正态分布（Discretised lognormal）；DSB3：三参数形式离散拉伸贝塔分布（Discretised stretched-beta (3 parameter form)）；DSB2：二参数形式离散拉伸贝塔分布（Discretised stretched-beta (2 parameter form)）。
