Comparison of the averaged percent errors in identifying diffusion coefficients (a) and transition probabilities (b) of the two-state system with a varying number of trajectories, shown in Fig. 2, c and d, using SPICER, 1d, and 3d analyses. The averaged percent error and shaded region are calculated the same way as for Fig. 3. The solid lines are the 10-point moving averages of raw data (scattered dots), and the shaded areas are the moving averages of the standard deviations of the parameters during the Markov chain Monte Carlo approach.
