Test of the variation in mass and size growths.

Results of the Generalized Estimating Equation (GEE) model procedures on mass growth (g/day), head growth (mm/day) and flipper growth (mm/day) according to egg treatment (control or androgen-treated egg), nest category (AA- or BB-nest), sex (male or female) and the presence of a sibling chick in the nest during early growth (0 or 1). All non-significant interactions were removed from the model during the backward procedure. df is always equal to 1. Significant P-values are marked in bold.本研究为广义估计方程（Generalized Estimating Equation, GEE）模型针对体重增长（克/天）、头部生长（毫米/天）及鳍肢生长（毫米/天）三项生长指标的建模分析结果，分析所纳入的影响因素包括：卵处理方式（对照组或雄激素处理卵）、巢类别（AA巢或BB巢）、雏鸟性别（雄性或雌性），以及生长早期巢内是否存在同窝雏鸟（取值为0或1）。在向后筛选建模流程中，所有无统计学显著性的交互项均已从模型中剔除。本次分析的自由度（df）恒为1，具有统计学显著性的P值已以粗体标注。
