Confounding of the mediator can be introduced into such a model by specifying a common component cause of the intermediate variable and the outcome.
In this linear model, we use the limma package [ 36] to fit the batch-corrected HaCaT data to a design matrix comparable to the P matrix inferred in CoGAPS by specifying a common intercept term, HaCaT cell type (HaCaT-EGFRWT, HaCaT-p65WT, HaCaT-HRASVal12D, or HaCaT-vector), and presence or absence of serum.
A presidential election would obviously be far trickier.Ever since Congress specified a common presidential-election day the first Tuesday after the first Monday in November the states have been obliged to go and vote on that day.
"That may sound like a tiny thing, but in the 1990s the RFID industry was convinced that it was in the portable-database business, and there was an incredible holy war that we fought for several years". The new EPC standard not only specifies a common format for the codes but creates a uniform system for matching the codes with detailed product information, which can be stored anywhere on the Web.
The first draft, due last month, would specify a common data format, making it easier for publishers to create a single file for each title that vendors can encrypt their own way.
As the initial versions of edgeR, we specify a common dispersion across conditions, i.e. As a consequence, the counts of differentially expressed genes have different variances in each condition.
In our data analyses of the five variables, we specified a common factor and five instrument-specific factors for each of the factors A, D, and E, which we denote Ac, Dc, and Ec.
Thus, it is hard to specify a common normal brain reference that would perfectly fit to all astrocytoma types with respect to their different tumor locations and age incidences.
Gene matching is generally done by specifying a gene identifier common to all experiments, matching on those identifiers, and then removing genes that are not represented across all experiments.
... As one researcher put it [in Nature], "It is theoretically and practically impossible to precisely specify a supposed common denominator for all these [GMO] products".... Why does this matter?
Finally, we assessed qualitative sex differences in the contribution of common environmental factors by specifying a free parameter in DOS twins that represents the correlation between the common environment of men and women (Rcdos).
