LinearFitBySvdCalculate Method

Fits a data set linearly to a given design matrix.

Namespace: Altaxo.Calc.Regression
Assembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3572.0 (4.8.3572.0)
Syntax
C#
Copy
public LinearFitBySvd Calculate(
	IROMatrix<double> xbase,
	IReadOnlyList<double> yarr,
	IReadOnlyList<double>? stddev,
	int numberOfData,
	int numberOfParameter,
	double threshold
)

Parameters

xbase  IROMatrixDouble
The matrix of x base values of the data set. Dimensions: numberOfData x numberOfParameters. The matrix is changed during the calculation!
yarr  IReadOnlyListDouble
The array of y values of the data set.
stddev  IReadOnlyListDouble
The array of y standard deviations of the data set. Can be null if the standard deviation is unkown.
numberOfData  Int32
The number of data points (may be smaller than the array sizes of the data arrays).
numberOfParameter  Int32
The number of parameters to fit == size of the function base.
threshold  Double
A treshold value (usually 1E-5) used to chop the unimportant singular values away.

Return Value

LinearFitBySvd
The linear fit result calculated by singular value decomposition.
