I have a little question regarding the counting-analysis of a CBC with alternative-specific design.
When an attribute has more levels than the number of concepts in a task is it possible to divide these probabilities by their sum for making comparisons across the attributes?
Example (each choice task including 3 concepts and a "None" option):
attribute levels of a conditional attribute X:
X1: 0.1 => 0.1/1.2 => 0.09
X2: 0.4 => 0.5/1.1 => 0.45
X3: 0,3=> 0.3/1.1 => 0.27
X4: 0,3=> 0.3/1.1 => 0.27
Thanks a lot!
