We excluded variance in frequency modulation because of high inter-correlation (i.e. r>0.8) with other parameters (variance in frequency modulation – variance in amplitude modulation, r = 0.87; variance in frequency modulation – mean frequency modulation, r = 0.85) [28].
We excluded variance of individual animals, only the factors related to the acquisition technique were taken into account, which included the effect of the imaging protocol and the instrument.
Therefore in such a model the difference between the GMO and its counterpart and the difference between the GMO and the mean of the reference varieties, which are both specific contrasts of the fixed factor GenotypeGroup, will be assessed against the proper residual variation, excluding the variance between genotypes.
After excluding the variance in repetition trial performance attributable to the MB context, ADHD group RTs remained significantly slower than control group.
After excluding the variance attributable to MB contexts, the data revealed that the ADHD group interference effect in PRBs was only evident in short CTI trials and could be successfully resolved in long CTI trials.
Specifiying the group × block × CTI finding reported in the presentation of the mixing cost accuracy data, the group factor nearly interacted significantly with CTI in PRBs (F (1, 42) = 3.5; p <.07) after excluding the variance attributable to MB repetition trial error rates.
Fig 2 shows the variance between individuals at the three time points and represents the variances of the random effects of the final mixed model (excluding residual variances).
However, when the polygynous males were excluded, standardised variance in annual genetic reproductive success (0.142) declined to 1.82 times the standardised variance in apparent social reproductive success (0.078, n = 161), suggesting that variation in mating status contributes substantially to the potential for sexual selection.
However, we cannot exclude residual variance in laboratory parameters.
During the analysis, SNPs were excluded for variance on the allele dosage ≤0.01.
Therefore, in order to exclude the variance of cognitive function associated with dementia as much as possible, we decided that the age of the subjects for this study was 55 years or under.
