Fig. 3.

Specification curve of the results of the Poisson QML regressions of response time (overall response time or local response time). The upper panel shows the estimated marginal effect of university on the response time for each of the 128 models. The lighter shaded area indicates the 90% confidence intervals. Each model represents a different combination of decisions about dependent variables and control variables. The confidence intervals indicate that the estimated marginal effect of university is significant for none of the models. In the lower panel, the dashboard depicts the details about the regressions. All Trend Dummies indicates where all trend dummies are included in the regressions.
