Highlights • Individuals vary in traits or in luck; both cause variance in life history outcomes.• The variance components are calculated from a multistate group-stage cohort model.• Sensitivity analysis shows how variance components relate to demographic parameters.• Both mortality and fertility affect the variance components.• Effects depend on life history timing, and the nature and mixture of differences.

作为生活史结果的方差:随机性和异质性贡献的敏感性分析

亮点 • 个人的特质或运气各不相同。两者都会导致生活史结果的差异。• 方差分量是根据多状态组阶段队列模型计算的。• 敏感性分析显示了方差分量与人口统计学参数的关系。• 死亡率和生育率都会影响方差分量。• 影响取决于寿命历史时间,以及差异的性质和混合。
