Evaluation of the zero-truncated modelling approach using synthetic data obtained from the HCP project, using voxelwise (top) and clusterwise (bottom) inference. The true number of missing contrasts (n0) for each one of the 12 datasets (6 for voxelwise thesholding and 6 for clusterwise thresholding) is shown in the second column. For each of the Negative Binomial and Delaporte methods, the estimated missing contrast count (), 95% bootstrap confidence interval for n0, AIC score and BIC score are shown (smaller AIC and BIC are better).
