Projection Methods

DirectOrthogonalization	Remove variation in X that is uncorrelated with the target y using Direct Orthogonalization (DO) [1]_ [2]_.
ExternalParameterOrthogonalization	Remove variation linked to known external nuisance parameters using External Parameter Orthogonalization (EPO) [1]_.
OrthogonalPLS	A transformer that removes variation in X that is orthogonal to the target y using Orthogonal Projection to Latent Structures (OPLS) [1]_.
OrthogonalSignalCorrection	Remove variation in X that is orthogonal to the target y using Orthogonal Signal Correction (OSC) [1]_ [2]_ [3]_.
