Orthogonal signal correction
Orthogonal Signal Correction (OSC) is a spectral preprocessing technique that removes variation from a data matrix X that is orthogonal to the response matrix Y.[1] OSC was introduced by researchers at the University of Umea in 1998 and has since found applications in domains including metabolomics.[2][3][4][5]
