my CBC exercise consists out of 13 random tasks and 2 fixed tasks.
I read somewhere that I can use the results of the fixed tasks to compare it with the general part-worth utilities of the 13 random choices to proof the
validity of my study.
How exactly would that work though?
Would I run an individual HB analysis for fixed task 1 and 2 and compare these part worth utilities with the one from the random sample?
Thanks in advance
