Of eleven significant gene-gene interaction models discovered in a cohort in which epistasis was examined as a source for phenotypic variance for HDL-C [ 48], only two epistasis pairs were tested for GxE interactions for the same HDL-C trait.
Parsing the variance in this fashion demonstrated that unknown factors within subjects remained the largest source of variance for all UAs, although some interesting patterns did emerge.
The fact that both aflatoxins (Dickens and Whitaker 1986) and OTA (Vargas et al. 2004) appear to display similar heterogeneity in sample lots indicate sampling is also likely the largest source of variance for the measurement of OTA in food items.
To account for this source of variance, E is always specified in the model.
Thus, we predict that a future study with a similar design as the present one, including a sufficiently large proportion of dyslexic and poor-comprehending children, would be in a good position to observe two distinct sources of variance for grammatical and for lexical skills, respectively.
The variance component for candidates was the largest source of variance (see the set of rows for 'c' in the 'effect' column).
Although several studies focuses on group therapy interventions, very few take control for this additional source of variance, potentially leading to significant bias.
This method did not account for age as a source of variance, so we used analysis of variance (ANOVA) as the primary method to rank genes according to the likelihood that there is a sex difference in expression after accounting for overall age effects (which have been reported previously).
We randomly perturbed the log ratio of the array data with Gaussian noise with a variance of 0.5 to model unknown sources of variance for each gene.
The highest source of variance related to views that interviewers have for particular candidates, because of their particular perspective or pre-conception, which accounted for nearly half (40%) of all the variance.
