FourPointStepEvaluationCreateFromIndices Method

public static FourPointStepEvaluation CreateFromIndices(
	IReadOnlyList<double> x,
	IReadOnlyList<double> y,
	double indexLeftOuter,
	double indexLeftInner,
	double indexRightInner,
	double indexRightOuter,
	bool useRegressionForLeftAndRightLine,
	(double LowerLevel, double UpperLevel) middleRegressionLevels,
	bool throwOnError = true
)

Parameters

x  IReadOnlyListDouble

The x array.

y  IReadOnlyListDouble

The y array.

indexLeftOuter  Double

The index of the left outer point.

indexLeftInner  Double

The index of the left inner point.

indexRightInner  Double

The index of the right inner point.

indexRightOuter  Double

The index of the right outer point.

useRegressionForLeftAndRightLine  Boolean

If set to true, a full regression is used for the left and right line. If set to false, only the inner and outer points are used to form the line.

middleRegressionLevels  ValueTupleDouble, Double

The regression levels for the middle line. For instance, if the value is set to (0.25, 0.75), then all points between 25% and 75% distance from the left and right line are used for the regression of the middle line.

throwOnError  Boolean  (Optional)

If true, any error in the evaluation will throw an InvalidOperationException. If false, no exception is thrown; instead, the error is stored and can be read out using the property Errors.
