Since the direction of comparison of the two organisms will give identical results under these conditions, one redundant half of the square matrix plot is left out.
Our comparison revealed that 16% to 22% of down-regulated genes were in common, and 25 to 27% of up-regulated genes were in common, depending on the direction of comparison (poplar to Arabidopsis, or the reverse; Figure 8).
By way of comparison, SURF integrates gradients to find the dominant direction.
The image data in each ROI was passed to the GLCM plugin (UMB GLCM features [ 30]), which was modified to allow the testing of numerous directions and distances of comparison.
If the TF T-values are of different signs, the highest absolute value of the two conditions dictates the direction of the comparison.
The direction of the comparison of imatinib against prostacyclins was shifted in favor of prostacyclins, which was expected due to the conservative assumption about the control arms.
(3) To avoid biases due to the direction of a comparison (e.g., A versus B is not the same as B versus A) (Wänke 1996), presentation of health states within one comparison should be randomly balanced.
The actual directionality of the change is irrelevant as it is dependent on the direction of the comparison (i.e. whether one compares group 1 with group 2 or the other way around).
We note that this is a very stringent correction, as only up to 20 hypotheses were considered for each eigensystem during the test stage (up to ten for either direction of the comparison).
These results include the effect of number of data snapshots, effect of different SNRs considering boresight and endfire directions and comparison of the array configurations (ULA, PA, L-shape and V-shape arrays) in AOA estimation performance, estimation accuracy as well as resolution, and also their computational complexity.
