We also made the a priori decision not to sum all 36 PCB congeners given that this data reduction technique assumes that summed components act via the same mechanism and elicit the same effects [ 26].
The flow field of movement vectors (arrows in D and G ) is plotted for each recovery condition as a heat map of the summed components along the noise response axis (E and F ) or grating response axis (H and I ).
From a test-retest reliability viewpoint such analyses may have an additional advantage: a priori one would expect a better reliability for summed components compared to single variables [ 31].
The four choices were assigned the values of one through four; the total score of physical functional status for each person was obtained by summing component scores across the 17 activities.
Subscale scores are obtained by summing component item scores (range, 4 20), with higher scores indicating greater use of a specific cognitive strategy.
(b) The observed sea level and the sum of components.
Totals are weighted data, therefore they may not equal the sum of components.
It is based on the morphological signal decomposition, a procedure that is used to model a facial image region as a sum of components.
The large majority of technological devices can be seen as the sum of components of heterogeneous nature (electrical, mechanical, thermal, software, etc).
A new method of testing completeness of a kinetic description was proposed, using the properties of the trace sum of components, i.e., the sum of all concentration dependences, each of which is started from maximal initial concentration.
