<h2>How to use the sigmoid page</h2>
<p>
The sigmoid page visualizes logistic regression probability:
<code>p = 1 / (1 + exp(-(b0 + b1x)))</code>.
</p>
<p>
Adjust <code>b0</code>, <code>b1</code>, and threshold <code>t</code> to see how decision boundaries and
probabilities change. You can also click the chart to add sample points and inspect classification outcomes.
