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. |
The 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).
