Hey there,
I conducted both an ACBC and CBC study for a research project. I am now required to document the D-efficiencies separately for both methods. I used the Sawtooth Software's "Test Design" procedure and found D-efficiencies for ACBC (for each respondent, which is absolutely fine), but no corresponding value for CBC.
For CBC I also included the OLS efficiency test and received efficiency-values for all attribute levels. So my question is: Is it possible to use these efficiency values to calculate a corresponding D-efficiency parameter for CBC? And if not, how might I get this?
I would be very pleased to receive your help!
