MultipleRegressionSvdT(IEnumerableTupleT, T, Boolean) Method

Find the model parameters β such that their linear combination with all predictor-arrays in X become as close to their response in Y as possible, with least squares residuals. Uses a singular value decomposition and is therefore more numerically stable (especially if ill-conditioned) than the normal equations or QR but also slower.

Namespace: Altaxo.Calc.LinearRegression
Assembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3179.0 (4.8.3179.0)
Syntax

Copy
public static T[] Svd<T>(
	IEnumerable<Tuple<T[], T>> samples,
	bool intercept = false
)
where T : struct, new(), IEquatable<T>, IFormattable

Parameters

samples  IEnumerableTupleT, T
Sequence of predictor-arrays and their response.
intercept  Boolean  (Optional)
True if an intercept should be added as first artificial predictor value. Default = false.

Type Parameters

T

[Missing <typeparam name="T"/> documentation for "M:Altaxo.Calc.LinearRegression.MultipleRegression.Svd``1(System.Collections.Generic.IEnumerable{System.Tuple{``0[],``0}},System.Boolean)"]

Return Value

T
Best fitting list of model parameters β for each element in the predictor-arrays.
