Syntax

public double[] GetAutoCovarianceX()

Public Function GetAutoCovarianceX As Double()

public:
array<double>^ GetAutoCovarianceX()

member GetAutoCovarianceX : unit -> float[]

Return Value

Type: Double
A double array of length maximumLag + 1 containing the variances and autocovariances of the time series x.

Exceptions

Exception	Condition
NonPosVarianceException	is thrown if the problem is ill-conditioned.
