Linear model of group performance predicted by topic focus.

Coefficient estimates of cross-sectional linear regression models for predicting a group’s size, growth, audience retention, and survival, using a group’s topic focus score as the lone predictor.本数据集收录了以群组主题聚焦得分为唯一预测变量的横截面线性回归（cross-sectional linear regression）模型的系数估计值，该类模型用于预测群组的规模、增长、受众留存与存续情况。
