Syntax
| C# |
|---|
public virtual void SetInitialEstimates( int init, double[] estimates ) |
| Visual Basic (Declaration) |
|---|
Public Overridable Sub SetInitialEstimates ( _ init As Integer, _ estimates As Double() _ ) |
| Visual C++ |
|---|
public: virtual void SetInitialEstimates( int init, array<double>^ estimates ) |
Parameters
- init
- Type: System..::.Int32
An input int indicating the desired initialization method for the initial estimates of the parameters.
- estimates
- Type: array<
System..::.Double
>[]()[]
An input double array of length nCoef containing the initial estimates of the parameters where nCoef is the number of estimated coefficients in the model.
Remarks
If this method is not called, init is set to 0.
| init | Action |
|---|---|
| 0 | Unweighted linear regression is used to obtain initial estimates. |
| 1 | The nCoef, number of coefficients, elements of estimates contain initial estimates of the parameters. Use of this option requires that the user know nCoef beforehand. |
estimates is used if init = 1. If this member function is not called, unweighted linear regression is used to obtain the initial estimates.
Exceptions
| Exception | Condition |
|---|---|
| System..::.ArgumentException | is thrown when init is not in the range [0,1] |
