 | PrincipalProjectionsRegressSupplementaryVariables Method (ReadOnlyDoubleMatrix) |
Gets the coefficients of the regression of each specified
supplementary variable on
the standardized principal variables.
Namespace: Novacta.Analytics
Assembly: Novacta.Analytics (in Novacta.Analytics.dll) Version: 2.0.0
Syntaxpublic DoubleMatrix RegressSupplementaryVariables( ReadOnlyDoubleMatrix supplementaryVariables )
Parameters
- supplementaryVariables
- Type: Novacta.AnalyticsReadOnlyDoubleMatrix
The supplementary variables.
Return Value
Type: DoubleMatrixThe regression coefficients of the specified supplementary variables on the standardized principal ones.
Exceptions| Exception | Condition |
|---|---|
| ArgumentNullException | supplementaryVariables is null. |
| ArgumentOutOfRangeException | The number of rows in supplementaryVariables is not equal to the number of points in the active cloud. |
RemarksThe matrix passed as supplementaryVariables must have as many rows as the number of points in the ActiveCloud, while the number of columns is the number of supplementary variables.
Returns a matrix having as many rows as the number of supplementary variables, and as many columns as the number of principal ones. Each row stores the estimated coefficients of a regression in which the corresponding supplementary variable is modeled on a collection of explanatory variables represented by the standardized principal variables (no intercept included).
