Recipes are tested in two-choice assays, where groups of over 100 individuals can choose one choice or the other. Preference for the group is computed as a preference index, a continuous variable that is between -1 and 1. <STRONG>Is there an experimental design that would help reduce the number of combinations to test in order to rank the recipes</STRONG> ? This seems to me similar to a choice design with a number of survey, the fundamental difference being that the response is not binary, but continuous.<BR />In this experimental approach, it is not possible to test the subjects individually, and we don't have access to individual choices. A non-choice design will be used as a screening method, but non-choice behavioural response is not informative enough.<BR />Thanks for your suggestions!<BR /><BR /></SPAN></P> Thu, 08 Jun 2023 21:07:07 GMT Alexa_Guigue 2023-06-08T21:07:07Z https://community.jmp.com/t5/Discussions/DoE-with-two-choice-experiments-continuous-response-variable/m-p/438333#M68697 <P><SPAN>We want to rank the preference&nbsp; of population of animals for n different recipes.
