Expand description

beadCountWeights (beadCountWeights.R): bead-count quality weights for Illumina BeadChips. Each probe’s variance is split into a technical component predicted from the bead-level coefficient of variation and bead counts, and a biological component recovered from the residual variance after fitting the design. The returned weights are 1 / (tech + bio), row-normalised to mean 1.

The biological variance is found per probe by Newton’s method, exactly as in limma’s internal .ilmn.biological.variance.

Structs§

BeadCountWeights
Result of bead_count_weights.

Enums§

BeadDispersion
How the bead-level dispersion is supplied. limma accepts either the per-probe standard deviation directly, or the standard error of the bead mean (in which case stdev = stderr * sqrt(nbeads)).

Functions§

bead_count_weights
beadCountWeights(y, x, design, nbeads, bead.stdev|bead.stderr, array.cv, scale).
