Parameters

xOfXRaw  Double

The x-values (wavelength, frequency, etc) of the unpreprocessed spectra.

matrixXRaw  IROMatrixDouble

Matrix of unpreprocessed spectra (a spectrum is a row in the matrix).

matrixYRaw  IROMatrixDouble

Matrix of unpreprocessed target variables (e.g. concentrations).

maximalNumberOfFactors  Int32

Maximum number of factors to calculate the cross PRESS for.

groupingStrategy  ICrossValidationGroupingStrategy

The strategy how to group the spectra for cross prediction.

preprocessSingleSpectrum  ISingleSpectrumPreprocessor

Information how to preprocess the spectra, here: how to process each spectrum separately.

preprocessEnsembleOfSpectra  IEnsembleMeanScalePreprocessor

Information how to preprocess the spectra, here: how to process the spectra ensemble.

regressionMethod  MultivariateRegression

The type of regression (e.g. PCR, PLS1, PLS2) provided as an empty regression object.

crossPRESS  IReadOnlyListDouble

The vector of CROSS press values. Note that this vector has the length numFactor+1.
