standardScreeningNumericTrait: Standard screening for numeric traits
Description
Standard screening for numeric traits based on Pearson correlation.
Usage
standardScreeningNumericTrait(datExpr, yNumeric)
Arguments
datExpr
data frame containing expression data (or more generally variables to be screened), with rows corresponding
to samples and columns to genes (variables)
yNumeric
a numeric vector giving the trait measurements for each sample
Value
List with the following components:
IDGene (or variable) identifiers copied from colnames(datExpr)
corPearsonPearson correlations of all genes with the trait
pvalueStudentStudent p-values of the correlations
qvalueStudentq-values of the correlations calculated from the p-values
AreaUnderROCarea under the ROC
Details
The function calculates the correlations, associated p-values, area under the ROC, and q-values
