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.
