linlog transformation
Philippe Rocca-Serra
A linlog transformation is a data transformation, described in PMID 16646782, whose input is a matrix [y_ik] and whose output is a matrix obtained by applying formula (9) of this paper, where values below an appropriately determined threshold (dependent on the row i) are transformed via a polynomial of degree 1, and values above this threshold are transformed via a logarithm.

This can be used for microarray normalization, e.g. to normalize the data from a two-channel expression microarray assay, as described in PMID 16646782.
