2. GPT-4 实现

为了增强上传图片中展示的Streamlit应用的可用性，考虑以下建议：

图表的动态更新：实现回调函数，当控制面板输入发生变化时，动态更新图表，无需手动刷新页面。
输入验证：包括输入验证，以防止用户输入无效数据，可能导致计算或可视化出现错误。
清晰的可视化标题：确保所有图表都有清晰的标题，描述它们代表的内容，使用户更容易理解所呈现的数据。
帮助文本/工具提示：添加帮助文本或工具提示，解释每个控制面板输入和图表代表的内容。这可以指导用户如何有效地与应用程序进行交互。
响应式布局：使用响应式布局，确保应用在不同的屏幕尺寸和设备上显示良好。
进度指示器：在进行需要时间的计算时，显示进度指示器，告知用户应用正在处理他们的请求。
可下载报告：提供下载结果的选项，例如“结果和决策”部分，作为PDF或CSV文件，以进行进一步分析或报告。
可访问性功能：考虑可访问性功能，如键盘导航和高对比度显示选项，以使残障人士能够使用该应用。

以下是一个示例，演示了如何将这些建议应用到使用Streamlit编写的代码中。这是一个概念性示例，需要根据应用程序中的具体功能和数据处理进行调整。

3. 请提供实现your_analysis_module的代码

prompt:

请提供实现your_analysis_module的代码

要创建在假设的Streamlit代码中引用的your_analysis_module，我们需要实现执行统计分析并根据输入参数生成图表的函数。例如，这些函数可能使用贝叶斯分析来更新有关点击率的信念。

以下是一个示例，说明您可能如何使用占位符函数来构建此模块，用于生成图表，因为实际的统计分析将取决于您的用例和数据的具体细节：
