def QuadraticRegression(
	inYValues: list[float],
	/,
	*,
	inXValues: list[float] | None = None
)
-> (

	outRSquared: float
)

Parameters

Name Type Default Description
Input value inYValues list[float] Sequence of ordinates
Input value inXValues list[float] | None None Sequence of abscissae, or {0, 1, 2, ...} by default
Output value outQuadraticFunction QuadraticFunction Quadratic function approximating the given point set
Output value outEstimatedValues list[float] The result of application of the computed function to the X values
Output value outResiduals list[float] Difference between an input Y value and the corresponding estimated value
Output value outRSquared float Coefficient of determination of output function
