Table 2.
Summary of runs test results and AIC and BIC scores for model fits to 30 randomly selected voxel TACs. Lowest AIC and BIC scores are underlined, indicating the best model according to that measure. AIC and BIC values have been calculated using both the scaled and unscaled versions as indicated in the table
