Restricted Variance Interactions in Entrepreneurship Research: A Unique Basis for Context-as-Moderator Hypotheses
展示受限方差交互作用在创业研究中的价值，帮助学者精确设定情境调节变量的角色，并用503家生物技术公司的数据说明该方法如何解释地理差异对联盟数量与IPO价值关系的影响。
In this methodological brief, we demonstrate the usefulness of the restricted variance (RV) interaction to entrepreneurship research. RV reasoning can help scholars to specify precise roles for contextual moderators. This specificity allows for strengthening of arguments and for testing of one of the reasons for an interaction. In some cases, it points to otherwise unexpected interaction patterns. We illustrate the power of RV reasoning with a data set of 503 biotech firms to show how RV explains geographic differences in the relationship between number of alliances and initial public offering value. Finally, we show how these interactions can be tested given typical distributions.
