MathRoutinesPolynomialRegression Method (Double, Double, Double, Int32)

LightningChart .NET Help

Calculate polymial line fit. Calculates polynomial factors, and uses these factors to solve Y values based on given X value array.

Assembly: Arction.Wpf.Charting.LightningChart (in Arction.Wpf.Charting.LightningChart.dll) Version: 10.3.1

Syntax

C++

Copy

public static double[] PolynomialRegression(
	double[] xInFactorization,
	double[] yInFactorization,
	double[] xValuesToFit,
	int order
)

Public Shared Function PolynomialRegression ( 
	xInFactorization As Double(),
	yInFactorization As Double(),
	xValuesToFit As Double(),
	order As Integer
) As Double()

public:
static array<double>^ PolynomialRegression(
	array<double>^ xInFactorization, 
	array<double>^ yInFactorization, 
	array<double>^ xValuesToFit, 
	int order
)

Parameters

xInFactorization: Type: SystemDouble
X values that are used to calculate the factors. This is the point set where the regression line is fitted to.
yInFactorization: Type: SystemDouble
Y values that are used to calculate the factors. Length must be equal to xInFactorization length.
xValuesToFit: Type: SystemDouble
X values whose Y values are to be solved, using the factors
order: Type: SystemInt32
Order of polynomial. Usually more than 3 shouldn't be used

Return Value

Type: Double
Fitted Y values, the length equals to xValuesToFit length. Returns null if failed.
