Problem Description

When running ANOVA analytics, you may encounter the following error:

Some combinations of the two categorical variables don’t seem to have any values. You might want to turn off the interaction.

This error occurs when your dataset has empty cells for certain factor combinations, making it impossible to calculate interaction effects between the two categorical variables.

Solution

To resolve this issue, disable the interaction term in your ANOVA model:

  1. Open the Analytics Properties Dialog
  2. Locate the Include Interaction option
  3. Set it to FALSE
  4. Click the Apply button.
