Description: The package implements a method for normalising microarray intensities,
        both between colours within array, and between arrays. The method uses a
	robust variant of the maximum-likelihood estimator for the stochastic model of
        microarray data described in the references (see vignette).
	The model incorporates data calibration (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.
