Fig 2. Dependence of the accuracy of the FIMSS entries on the number of pseudo data sets.
Each panel shows one entry of FIMSS. Note that the 2 × 1 entry is identical to the 1 × 2 entry due to the symmetry of the Fisher information matrix. The x-axis shows the number of pseudo data sets M used for calculating the sample mean (shown as solid line) of Eq 7. Gray color indicates the area from sample mean plus / minus one standard deviation. As the width of the gray are is decreasing, the accuracy increases and an acceptable accuracy is reached at values around M = 200.
