Default Re: Lecture 3 Q&A independence of parameter inputs

In this case the features are clearly not independent. Would this be seen as a questionable procedure?
Could you use the [lecture3] macro (see the "Including a lecture video segment" thread at the top) to pinpoint the part you are referring to? Thank you.
