Pivoted Design

[Christoph_Ihl]

Dear all,

we want to construct a design that is pivoted from a status quo alternative. However, some attributes have upper and lower bounds. So for respondents already close to / at the bounds, a pivoted design may include stimuli out of the logical range. Are constraints possible within pivoted designs? Any other work around?

Thanks and best regards,
Christoph

Apologies for late reply.
It is currently not possible to put such constraints on the resulting levels.

All I can think of, is creating a series of designs for different people in advance, to ensure they are within the bounds.
