A third party conducted a CBC survey and merged that survey with the non conjoint part coded on another software. For calculating the utilities, we had requested them to provide the raw data to us which include all the task columns, Version and DesignID column along with the .SSI and design file. They provided everything except for DesignID column.
Is there a way to get that information? Also, is it the case that itis going to be the same for all respondents? Noticed that in the test data we generated after importing the design file into the survey.
Thanks in advance
