In Chapter 16 GLM, page 50, is there an error in the table of exposure? From the table, the level unknown for the factor colour is not perfectly correlated with the level unknown for the factor number of doors, as there are 5 exposures for which the number of doors are unknown but colour is black, as is the case for the 'near aliasing' example in the next page. Please advise. Thank you.
Yes, there's an error in the Core Reading. Well spotted! The '5' shouldn't be there in the first table. We'll update the Corrections document and let the Profession know.
