Single Channel Analysis of Two-Color Microarrays

Description

This page gives an overview of the LIMMA functions fit linear models to two-color data in terms of the individual channels.

The function intraspotCorrelation estimates the correlation between the two channels. The regression function code{lmscFit} takes the correlation as an argument and fits linear models to the two-color data as in terms of the individual log-intensities. The function array2channel converts two-color format target data frames to single channel format, to facilitate the formulation of the design matrix.
