I once interviewed at a biostats shop where the interviewer kept using the word "responses" to refer to feature values. I could not pin him down on the problem statement. Pretty sure that dumbass thinks I'm a dumbass.
That doesn't make sense. By "response" he probably meant response variables, as in the dependent variables. Features would be the independent variables (or "predictors" in some stats/biostats circles).
Precisely! Post hoc, I figured out that he must have meant responses to an assay, which makes sense in context, but like, I would have expected someone with any stats background whatsoever to be able to clarify.
