Implementation of a gamma deconvolution for background correction.
Description
SNP and methylation microarrays exhibit a different distribution of signal
and background intensities than expression microarrays. The flexibility of
the gamma distribution suits the observed signal and background intensity
distributions well, encompassing as a special case the normal-exponential
convolution (the de facto standard for expression background correction).
In addition, a signal/noise mixture model is implemented for empirical
deconvolution of cross-hybridization between probe alleles.
