Interaction in Linear versus Logistic Models: A Substantive Illustration Using the Relationship between Motivation, Ability, and Performance
以高中毕业这一二元绩效指标为例，研究动机与能力的交互效应在逻辑模型和线性概率模型中分别呈现正负相反的结果，并探讨差异原因及发生条件。
A binary performance measure (high school graduation) is examined as a function of motivation (educational goal), ability (scores in an intelligence test), and their interaction. The interaction was positive when a logistic model was used and negative when a linear probability model was used. The reason for the difference in the results of the two models is examined, and the conditions under which this difference occurs are discussed.
