Performs a multivariate linear regression. Select in the dialog a target column (combo box on top), i.e. the response. The two lists in the center of the dialog allow you to include only certain columns which represent the (independent) variables. Make sure the columns you want to have included being in the right "include" list. See article in wikipedia about linear regression for an overview about the topic.

- Target
- To select the target column. Only columns with numeric data are allowed.
- Values
- To specify the independent columns the should be included in the regression model. Numeric and nominal data can be included, whereby for nominal data dummy variables are automatically created as described in section Categorical variables in regression.
- Predefined Offset Value
- By default, the regression model includes a constant term. Selecting this option the given constant term is used. The value works like a user defined intercept.
- Missing Values in Input Data
- Define wether missing value in the input are ignored or whether the node execution should fail on missing values.
- Scatter Plot View
- Specify the rows that shall be available as data points in the scatter plot view.

- Linear Regression Result View
- Displays the estimated coefficients and error statistics.
- Linear Regression Scatterplot View
- Displays the input data along with the regression line in a scatterplot. The y-coordinate is fixed to the response column (the column that has been approximated) while the x-column can be chosen among the independent variables with numerical values. Note: If you have multiple input variables, this view is only an approximation. It will fix the value of each variable that is not shown in the view to its mean. Thus, this view generally only makes sense if you only have a few input variables.
