Syntax

public virtual void Compute(
	double[,] x,
	double[] y,
	double[] weights,
	double[] frequencies
)

Public Overridable Sub Compute ( 
	x As Double(,),
	y As Double(),
	weights As Double(),
	frequencies As Double()
)

public:
virtual void Compute(
	array<double,2>^ x, 
	array<double>^ y, 
	array<double>^ weights, 
	array<double>^ frequencies
)

abstract Compute : 
        x : float[,] * 
        y : float[] * 
        weights : float[] * 
        frequencies : float[] -> unit 
override Compute : 
        x : float[,] * 
        y : float[] * 
        weights : float[] * 
        frequencies : float[] -> unit

Parameters

x: Type: SystemDouble
A double matrix containing the observations of the candidate (independent) variables.
y: Type: SystemDouble
A double array containing the observations of the dependent variable.
weights: Type: SystemDouble
A double array containing the weight for each of the observations.
frequencies: Type: SystemDouble
A double array containing the frequency for each of the observations of x.

Exceptions

Exception	Condition
NoVariablesException	is thrown if no variables can enter any model
NegativeFreqException	is thrown if a frequency is less than zero.
NegativeWeightException	is thrown if a weight is less than zero.
TooManyObsDeletedException	is thrown if more observations have been deleted than were originally entered
MoreObsDelThanEnteredException	is thrown if more observations are being deleted from the output covariance matrix than were originally entered
DiffObsDeletedException	is thrown if different observations are being deleted from the return matrix than were originally entered

Remarks

The number of columns in x must be equal to the number of variables set in the constructor.
