As well, we allow for variance heterogeneity.
To allow for variance heterogeneity, a variance-by-group structure was included if diagnostic plots and AIC values indicated violation of the residual homogeneity assumption (CRP and TNFα).
Taking the variety of distributions of environmental impact for every stage of the production process would allow for variance estimation of the environmental impact of a food group.
This problem is handled by using statistical analyses that incorporate information about time until death and allow for variance in group differences over time.
While aggregation of CpG site data can recover some power for differential methylation detection, we recommend the use of SuBLiME with higher read coverage and at least two replicates in each group, to allow for variance estimation.
Other methods that incorporate soft thresholding allow for variance in the actual correlation value based on distribution of node degree [ 29]; this method goes on to use topological overlap matrices to identify modules of functional significance with great accuracy.
To account for variation in under-enumeration between cancer registries, the application of random- and fixed-effect regression (using Stata xtreg with 'fe' and 're' options) was tested, to model and allow for variance in NMSC rates within and between registries.
All parameters were set to default values, with the exception of the prior of the age of the clade formed by the Sardinian species and their sister, which was set to a normal distribution with mean of 33 MY and a standard deviation of 2.0 MY (corresponding to a 95% confidence interval of 28.8 and 36.3 MY) to allow for variance from stochastic sampling error of nucleotide changes [ 41].
The process estimates point values between sampled locations in a grid using an inverse distance weighing of nearby sample points and allowing for variance of each sample (Isaaks and Srivastava 1989).
This invokes the same number of new parameters as the F81 model, but allows for variance in asymmetry across sites.
