How to Validate a Linear Discriminant Analysis Model

This article describes how to create a Prediction Accuracy Table (Classification Table) to validate a Linear Discriminant Analysis model. 

Requirements

• A Displayr document containing a Linear Discriminant Analysis output created using a test/train sample split as described here. 

Please note this requires the Data Stories module or a Displayr license.

Method

1. Select the Linear Discriminant Analysis output on the page.
2. From the Filter(s) drop-down box in the object inspector, choose Testing sample. 
3. Within Diagnostics, click on Prediction-Accuracy Table.

The output from my example is shown below, with a training set accuracy of 57.81%.
