| <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. | |
