在同伴群体行为的研究中，同伴群体行为的直接测量往往是不可用的，因此被调查受访者的感知所取代。这项研究表明，回归估计是不一致的，当正确测量的群体行为的自变量被替换为调查受访者的感知措施。这种不一致性有三个来源：将自己的行为投射到群体上，重新调整群体的边际效应，以及简单的随机测量误差。我们讨论了为什么每个效果可能会导致不一致，推导出公式的概率限制，以量化其影响，并说明与青少年吸烟和饮酒的三个例子。
In studies of peer group behavior, the direct measure of peer group behavior is often not available, and so is replaced by perceptions from survey respondents. This study shows that regression estimators are inconsistent when the correctly measured independent variable of group behavior is replaced with perceived measures from survey respondents. The inconsistency is due to three sources: projection of own behavior onto the group, rescaling the marginal effect of the group, and simple random measurement error. We discuss why each effect may cause inconsistency, derive formulas for the probability limit to quantify their effects, and illustrate with three examples of adolescent smoking and drinking.
