if columns are added.
|
| HasInterceptParameter |
Returns true if the model has an intercept parameter; otherwise,
false.
|
| Intercept |

if rows are added.
|
Methods| Name | Description | |
|---|---|---|
 | AddInterceptParameter |
Adds an intercept parameter to the model and recalculates the model parameters.
|
| AddObservation |
Adds the given observation to the model, and recalculates the model parameters.
|
| AddObservations |
Adds the given observations to the model, and recalculates the model parameters.
|
| AddPredictor |
Adds a predictor to the model, and recalculates the model parameters.
|
| AddPredictors |
Adds predictors to the model, and recalculates the model parameters.
|
 | FirstColumnIsAllOnes(DFNumericColumn) |
Checks if the given numeric column contains all 1's
|
| FirstColumnIsAllOnes(DoubleMatrix) |
Convienence method for determining if the first column of a matrix
is all ones.
|
| FirstColumnIsAllOnes(DoubleVector) |
Determine if the vector is all 1's
|
| RecalculateParameters |
Recalculates the model parameters.
|
| RemoveInterceptParameter |
Removes the intercept parameter from the model, and recalculates the model parameters.
|
| RemoveObservation |
Removes the row at the indicated index from the predictor matrix and the
corresponding element from the observation vector, and recalculates the model
parameters.
|
| RemoveObservations |
Removes the specified rows from the predictor matrix, and recalculates the model
parameters.
|
| RemovePredictor |
Removes the specified predictor from the model, and recalculates the
model parameters.
|
 | RemovePredictors |
Removes the specified predictors from the model, and recalculates the model
parameters.
