Response variable

The numeric outcome, or response, variable of interest.


Select one or more variables that can be used to predict the value of the response variable. This could be a variable or predicted values from a model (e.g., from a regression estimated using Model > Linear regression (OLS) or a Neural Network estimated using Model > Neural Network (ANN)).

If a filter is active (e.g., set in the Data > View tab) generate results for All data, Training data, Validation data, or Both training and validation data. If no filter is active calculations are applied to all data.


Predictions were derived from a linear regression and an neural network with two nodes in the hidden layer on the diamonds data. The variables price and carat were log-transformed prior to estimation.The data is available through the Data > Manage tab (i.e., choose Examples from the Load data of type drop-down and press Load examples). The predictions shown below were generated in the Predict tab.

The test statistics show a small, but consistent, advantage for the ANN.
