"""Variance stabilization and calibration for microarray data.
|
|
|
|
The package implements a method for normalising microarray intensities,
|
|
and works for single- and multiple-color arrays. It can also be used for
|
|
data from other technologies, as long as they have similar format. The
|
|
method uses a robust variant of the maximum-likelihood estimator for an
|
|
additive-multiplicative error model and affine calibration. The model
|
|
incorporates data calibration step (a.k.a. normalization), a model for
|
|
the dependence of the variance on the mean intensity and a variance
|
|
stabilizing data transformation. Differences between transformed
|
|
intensities are analogous to "normalized log-ratios". However, in
|
|
contrast to the latter, their variance is independent of the mean, and
|
|
they are usually more sensitive and specific in detecting differential
|
|
transcription."""
