07.SingleChannel: Topic: Individual Channel Analysis of Two-Color Microarrays
Description
This page gives an overview of the LIMMA functions fit linear models to two-color microarray data in terms of the log-intensities rather than log-ratios.
The function intraspotCorrelation
estimates the intra-spot correlation between the two channels.
The regression function lmscFit
takes the correlation as an argument and fits linear models to the two-color data in terms of the individual log-intensities.
The output of lmscFit
is an MArrayLM
object just the same as from lmFit
, so inference proceeds in the same way as for log-ratios once the linear model is fitted.
See 06.LinearModels.
The function targetsA2C
converts two-color format target data frames to single channel format, i.e, converts from array-per-line to channel-per-line, to facilitate the formulation of the design matrix.See Also
