我们提供了统计测量和额外的分析，表明我们的原始分析是合理的。我们使用广义线性混合模型来解释程序与程序之间的差异，程序作为随机效应而不使用分层，并发现GRE-P（研究生入学考试物理测试）效应与我们之前的研究结果没有什么不同，从而减轻了对撞机偏差的担忧。每个变量的方差膨胀因子都很低，表明多重共线性不是一个问题。我们表明，范围限制对于GRE- p或GRE- v （GRE口头）来说不是问题，对于GRE- q （GRE定量）来说只是一个小问题。最后，我们使用模型质量的统计度量来表明我们发表的模型比几个备选模型更好或等效。
We provide statistical measures and additional analyses showing that our original analyses were sound. We use a generalized linear mixed model to account for program-to-program differences with program as a random effect without stratifying with tier and found the GRE-P (Graduate Record Examination physics test) effect is not different from our previous findings, thereby alleviating concern of collider bias. Variance inflation factors for each variable were low, showing that multicollinearity was not a concern. We show that range restriction is not an issue for GRE-P or GRE-V (GRE verbal), and only a minor issue for GRE-Q (GRE quantitative). Last, we use statistical measures of model quality to show that our published models are better than or equivalent to several alternates.
