standard / ## Figure 7.
Illustration of subjects raw performances in the boxplots titled 'Data' (the red lines
indicate the median, the blue boxes extend from the upper to the lower quartile values,
the whiskers show the most extreme points within 1.5 times the inter-quartile range
and the red plus signs indicate outliers) and bootstrapped performances with linear
adjustments (graphic lines titled 'Means and linear fits'; vertical lines show the
standard deviation of the bootstrapped means and the red lines the linear fits). Distribution plots titled 'Non linear F values' show the distributions of F values
measuring the distances between the bootstrapped data and the bootstrapped regression
lines. Non central distributions suggest non linear effects; significant effects are
marked with a star. For all graphics, numbers below the graphics stand for the different
groups: (1) LCD/LLN, (2) LCD/HLN, (3) HCD/HLN, (4) HCD/LLN, (5) Controls. Note that
although linear adjustments can be observed based on the ranking of the means, the
different behavioural tests have different ranking (in contrast to the behavioural
tests illustrated on the figure 6). The last (right end side) graphics show the bootstrapped
data (blue circles) with smoothed interpolated data (in green – piecewise cubic hermite
interpolating polynomial).
