shrinkageMetric {variancePartition} | R Documentation |
Evaluates the coefficient from the linear regression of s2.post ~ sigmaSq
. When there is no shrinkage, this value is 1. Values less than 1 indicate the amount of shrinkage.
shrinkageMetric(sigmaSq, s2.post)
sigmaSq |
maximum likelihood residual variance for every gene |
s2.post |
empirical Bayes posterior estimate of residual variance for every gene |
Shrinkage metric for eBayes quantifying the amount of shrinkage that is applied to shrink the maximum likelihood residual variance to the empirical Bayes posterior estimate
