<p><a href="https://stats.stackexchange.com/questions/519216/classification-performance-metrics-for-logistic-regression-from-the-properties-o">My question</a> was closed as a duplicate of <a href="https://stats.stackexchange.com/questions/50609/validation-data-splitting-into-training-vs-test-datasets">another question</a>.</p>
<p>I was asking for a formula, if any, to compute accuracy for a logistic regression without using a separate test set. For instance (I am just making it up):
<span class="math-container">$ \text{accuracy} = (\hat{\sigma}^2/N) \hat{y}^2 \text{Var}(\hat{\beta})$</span>
or whatever.</p>
<p>The &quot;duplicate&quot; question would have me compute the accuracy using the bootstrap. Which of course is just averaging many test sets.</p>
<p>How is that an answer?</p>
<p>I think my question wasn't clear. Can I modify it and have the question re-opened?</p>
