Example of a Neural Network
Results are provided for both the training and validation sets. Use the results of the validation set as a
representation of the model’s predictive power on future observations.
The R-Square statistic for the Validation set is 0.838, signifying that the model is predicting well on data
not used to train the model. As an additional assessment of model fit, select Plot Actual by Predicted from
the Model red-triangle menu. The plot is shown in Figure 10.7.

The points fall along the line, signifying that the predicted values are similar to the actual values.
To get a general understanding of how the X variables are impacting the predicted values, select Profiler
from the Model red-triangle menu. The profiler is shown in Figure 10.8.
