Dependence of the accuracy of the FI_MSS entries on the number of pseudo data sets.

The x-axis shows the number of pseudo data sets M used for calculating the 2 × 2 entry of FI_MSS, the mean is shown as solid line. Gray color shows the area from sample mean plus / minus one standard deviation. As the width of the gray area is decreasing, the accuracy is increasing. One can see that already small values as M = 400 give a good approximation.
