I have a CBC study with a dual respnse no choice. No I want to test validity by comparing actual choices in the hold-out task with coice simulator estimates. If I am correct this is done by conducting a "counts" analysis of the hold-out task and comparing the obtained shares with those of the choice simulator for the hold-out task based on HB utilities for instance.
In the choice simulator I can choose to include the none option or not. However, I did not find this option in the counts analysis. How can I include the none option in the counts analysis? I only received the shares of the different alternatives without consideration of the dual-response no choice.
Thank you and kind regards
