<p>I want to start a bounty again for this question (<a href="https://stats.stackexchange.com/questions/468189/how-do-i-perform-an-actual-posterior-predictive-check">How do I perform an actual &quot;posterior predictive check&quot;?</a>), 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?</p>
