I forgot a minus sign everywhere and I made a question wrong.

I asked The differential entropy cannot be negative for pdf in (0,1) but the question should have been positive instead of negative.

The accepted answer gives an answer to the negative question and an answer for the positive question in the comments.

I want to edit the question, but if I edit it, the accepted answer will not correspond at all and will be very misleading.

  • Is it ok if I create a second question using positive and answer it based on the comments of the negative answer? (adding a reference)
  • Or should I edit it?

One should not edit a question in such a way that it renders existing good answers invalid. If you do not note the error in time, just leave the post around if it makes sense.

Yes, it is alright to ask the originally intended question in a new post, and it is also fine to self-answer it if you want to do this.

To avoid confusion, I recommend to write a comment on the new post, or even in the new post, that explains the situation.
