When a uniform linear array (ULA) is used, the estimation error can be reduced even more by averaging the correlation coefficients over all antenna pairs spaced by the same distance, before using the LUT, instead of averaging the individual AS estimates over all antenna pairs.
Briefly, quality scores Q(L i k ) at fragment lengths L i k in electropherogram P k (k = {1,..., m}) are estimated by a windowing calculation of local average correlation coefficients between P k and the other electropherograms (for details, see [ 12]).
At the regional level, the value in the table was obtained by averaging the correlation coefficient over the 21 regions of France.
In order to incorporate the replicates at each time point, we repeated the calculations by randomly sampling over the replicates at each time point and by calculating an average correlation coefficient from the resampled curves afterwards.
In a noninflammatory situation (represented by Balb/c mice), the average correlation coefficient of analytes included in the model did not show a negative association with salivary flow (r = -0.076).
The authors used the ρ > 0.455 threshold by determining that the average correlation coefficient of expression in 1000 randomly chosen gene/product pairs from 23 cancer cell lines was 0.001, and that the selected value of ρ of 0.455 provided the 95% confidence interval of the ρ distribution.
To avoid inflating the average correlation coefficient by including probes that would have been expected to be correlated in the absence of the G-spot effect, within each subgroup only the first probe in any probe set was used.
Romo et al. (2003) observed a loss in accuracy caused by positive correlations (with an average correlation coefficient of 0.12) between neurons tuned to the same frequency, but this was partially offset by an improvement caused by positive correlation between neurons tuned to different frequencies.
