Performance of simultaneous multiple regression models.

The variables developed in prior analyses were used in one multiple regression model, predicting tweet rate by a variety of factors. All contribute significantly. Proportion variance uniquely associated with each variable in the model is shown, by entering it last into the regression. Note that models include all interaction terms among our primary variables analyzed above (speaker, interruptions, etc.).
