Assessing the dependence of <i>f</i>_<i>res</i> and <i>Q</i>_<i>Z</i> on the linear correlation.

<p>a. Parameter values for each model were changed along a line parallel (‖, blue) to the correlation line (black) or along a perpendicular line (┴, grey). This was done for models with high (cyan; a1), low (red; a2) and intermediate (grey; a3) models. For each model and each line, ‖ or ┴, we fit a line to the relative change in either <i>f</i>_res or <i>Q</i>_Z as a function of the relative change in . b. The sensitivity values of <i>f</i>_<i>res</i> or <i>Q</i>_<i>Z</i> to ‖ or ┴ are shown for the three groups.
