Apply pre-specified sample weights by scaling existing precision weights
Details
Apply pre-specified sample-level weights to the existing precision weights estimated from the data. While the limma::voomWithQualityWeights
function of Lui et al. (2015) estimates the sample-level weights from voom
fit, here the weights are fixed beforehand.
