StepwiseRegression.Intercept Property

StepwiseRegressionIntercept Property

Returns the intercept.

Namespace: Imsl.Stat
Assembly: ImslCS (in ImslCS.dll) Version: 6.5.2.0

Syntax

public virtual double Intercept { get; }

Public Overridable ReadOnly Property Intercept As Double
	Get

public:
virtual property double Intercept {
	double get ();
}

abstract Intercept : float with get
override Intercept : float with get

Return Value

Type: Double
A double containing the intercept.

Remarks

The intercept is computed as follows:

$\beta_0=\bar{y}-\sum_{i=1}^{n}\beta_i \bar{x}_{i-1}$

where $\bar{y}$ is the mean of the dependent variable y, $\beta_i$ are the coefficients, and $\bar{x}_i$ are the mean values for each independent variable

in the final model. If the covariance matrix is used for input, use method SetMean to specify the means of the variables. If x and y are used for input, the means are computed internally and do not need to be specified.
