(`confusion-matrix-explorer`) contains a PyShiny app for exploring how changing a decision threshold affects a binary classifier confusion matrix and related metrics (sensitivity, specificity, precision, etc.).\n\n## Launch the App In Your Browser\n\nClick here: [**Launch the Confusion Matrix Explorer**](https://denisecase.github.io/confusion-matrix-explorer/app/)\n\nThe app runs in your browser using **Shinylive** (Pyodide), no installation needed.\n\n\n## About the App\n\nThe **Confusion Matrix Explorer** app demonstrates how changing the decision threshold (the vertical T line) affects the confusion matrix and related metrics (sensitivity, specificity, etc.) for a binary classification problem.\n\nHow to use:\n\n- Use the sidebar upper slider to vary the decision threshold.\n- Use the sidebar lower slider to vary the number of bins in the histogram.\n- Compare the as you raise (or lower) the decision threshold.\n\nTo learn more:\n\n- See [ABOUT.md](./docs/ABOUT.md).\n\n## Optional: Run on Your Machine\n\n- To run on your machine, see the [Home Page](index.md).\n- To make modifications, see [DEVELOPER.md](./docs/DEVELOPER.md)\n\n---\n\n## Screenshot (Raise the Bar)\n\n![Raise the bar](./docs/images/bar_up.png)\n\n## Screenshot (Default)\n\n![Default](./docs/images/bar_center.png)\n\n##
