Figure 2
Distribution of the normalized deviations of each model (blue histogram) versus the normalized Gaussian distribution (in red) for (S)-(+)-ibuprofen. The blue curve is the best-fit Gaussian distribution to the histogram. The normal probability plot (blue dotted line) represents the normalized deviations versus the theoretical quantiles of (S)-(+)-ibuprofen for all the data with N = 3855 reflections (not including 37 single reflections having zero delta). The straight line is the best-fit line to the normal probability plot. (a) Original model normalized deviations and normal probability plot of original uncorrected error estimates data (model 0). (b) Adjusted normalized deviations and normal probability plot of model 1. (c) Adjusted normalized deviations and normal probability plot of model 2. (d) Adjusted normalized deviations and normal probability plot of model 3.
