I know that deleting one's own question is not encouraged on this site but I'm curious about this situation. This question prompted this inquiry. This began as a simple question about how to interpret the
predict.lm() function in R. As Michael Chernick and I continued to question the original poster to get clarification, it turns out he was using OLS to model a proportion, which is usually a poor approximation. After Michael and I both agreed that he, at least, needed to transform the response, a new line of questioning began.
At this point, the question was pretty much unrelated to the original question, and I suggested that he start a new question and consider deleting this one - is this the correct recommendation? He's surely no longer interested in the question he was originally asking and there were no answers, although I suppose a future person could be interested (although in this case simply reading the help page would've done the job). How about when there are answers to the question but they are now obsolete given the modification? Perhaps in that case we would just start a new question but keep the old one?
Edit: It turns out the original poster did delete the question per my suggestion. My question still stands - was this bad advice?
