Time until reaching a conclusion in sequential analysis for different true acceleration factors (panels). The upper part of each histogram shows distribution of times until reaching the correct conclusion (deep purple), the lower part of the histogram shows distribution of times until reaching the wrong conclusion (light green), and the double sided bar at the end shows the proportion of undecided sequential analyses at the end of the trial (grey). Methods: Bayesian model-averaging (monitored every month, first row) and model selection over parametric families with: Bayes factors (monitored every month, second row), AIC (with 20 interim analyses, third row), and BIC (with 20 interim analyses, fourth row)
