I want to start a bounty again for this question (How do I perform an actual "posterior predictive check"?), since it hasn't received enough attention and no answer has been provided yet. However, I don't see the option "start a bounty," I only see the option "question eligible for a bounty since may." What is preventing me to start a bounty?
If you've already offered a bounty of 100 rep., the minimum spend for the next bounty is 200 rep.—and you haven't got enough yet. See https://stats.stackexchange.com/help/bounty for details.
1$\begingroup$ Got it, thanks. Next time I will start with 50 and gradually build up. $\endgroup$– user272422Jun 8, 2020 at 17:40
1$\begingroup$ @Glorfindel I guess I screwed up then. Hopefully if people tolerate my snark comments and upvote my answers and I will get the 200 to offer the bounty again. $\endgroup$– user272422Jun 8, 2020 at 20:27
