SyntaxC#
public class PLS2Regression : MultivariateRegression
The PLS2Regression type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | PLS2Regression | Initializes a new instance of the PLS2Regression class |
Properties| Name | Description | |
|---|---|---|
 | CalibrationModel | |
 | InternalCalibrationModel | (Overrides MultivariateRegressionInternalCalibrationModel) |
| NumberOfFactors |
Returns the number of factors calculated during the analysis.
(Inherited from MultivariateRegression) |
| NumberOfSpectralResiduals |
This returns the number of spectral residuals. This is normally 1, but for the PLS1 analyis, it is the NumberOfY.
(Inherited from MultivariateRegression) |
| PRESS |
Methods| Name | Description | |
|---|---|---|
| AnalyzeFromPreprocessed |
Creates an analyis from preprocessed spectra and preprocessed concentrations.
(Inherited from MultivariateRegression) |
 | AnalyzeFromPreprocessedWithoutReset |
Creates an analyis from preprocessed spectra and preprocessed concentrations.
(Overrides MultivariateRegressionAnalyzeFromPreprocessedWithoutReset(IROMatrixDouble, IROMatrixDouble, Int32)) |
 | CalculateXLeverageFromPreprocessed | |
| CreateFromPreprocessed | Creates an analyis from preprocessed spectra and preprocessed concentrations. |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| ExecuteAnalysis | Partial least squares (PLS) decomposition of the matrizes X and Y. |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetPredictionScoreMatrix | Get the prediction score matrix. To get the predictions, you have to multiply the spectras to predict by this prediction score matrix (in case of a single y-variable), this is simply the dot product. |
| GetPredictionScores |
Calculates the prediction scores.
(Inherited from MultivariateRegression) |
| GetPRESSFromPreprocessed | (Overrides MultivariateRegressionGetPRESSFromPreprocessed(IROMatrixDouble)) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| GetXLeverageFromPreprocessed |
Calculates the spectral leverage from preprocessed spectra.
(Inherited from MultivariateRegression) |
| GetXLeverageFromRaw |
Calculates the spectral leverage from raw spectra.
(Inherited from MultivariateRegression) |
| InternalGetPredictionScores |
Calculates the prediction scores (for use withthe preprocessed spectra).
(Overrides MultivariateRegressionInternalGetPredictionScores(Int32, IMatrixDouble)) |
| InternalGetXLeverageFromPreprocessed | (Overrides MultivariateRegressionInternalGetXLeverageFromPreprocessed(IROMatrixDouble, Int32, IMatrixDouble)) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| Predict | |
| PredictedYAndSpectralResidualsFromPreprocessed |
This predicts concentrations of unknown spectra.
(Overrides MultivariateRegressionPredictedYAndSpectralResidualsFromPreprocessed(IROMatrixDouble, Int32, IMatrixDouble, IMatrixDouble)) |
| PredictYFromPreprocessed |
This predicts concentrations of unknown spectra.
(Inherited from MultivariateRegression) |
| PredictYFromRaw |
Predicts y values from raw (unpreprocessed) spectra.
(Inherited from MultivariateRegression) |
| Reset | (Overrides MultivariateRegressionReset) |
| SetCalibrationModel | (Overrides MultivariateRegressionSetCalibrationModel(IMultivariateCalibrationModel)) |
| SpectralResidualsFromPreprocessed(IROMatrixDouble, Int32) |
This calculates the spectral residuals.
(Inherited from MultivariateRegression) |
| SpectralResidualsFromPreprocessed(IROMatrixDouble, Int32, IMatrixDouble) |
This calculates the spectral residuals.
(Inherited from MultivariateRegression) |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
