# A股收益率分布/统计特征分析
## 数据源
```bash
SCRIPTS="$SKILLS_ROOT/cn-stock-data/scripts"
python "$SCRIPTS/cn_stock_data.py" kline --code [CODE] --freq daily --start [日期]
python "$SCRIPTS/cn_stock_data.py" quote --code [CODE]
python "$SCRIPTS/cn_stock_data.py" finance --code [CODE]
```
## Workflow
### Step 1: 获取K线收益率序列
### Step 2: 描述性统计
均值/中位数/标准差/偏度/峰度/最大值/最小值
### Step 3: 正态性检验
- Jarque-Bera检验
- Shapiro-Wilk检验
- QQ图分析
### Step 4: 分布拟合
拟合t分布/GED分布/混合正态,比较拟合优度
### Step 5: 输出
| 维度 | formal | brief |
|------|--------|-------|
| 统计量 | 完整描述性统计 | 偏度/峰度 |
| 正态检验 | 多种检验结果 | 是否正态 |
| 分布拟合 | 最佳拟合分布 | 分布类型 |
默认风格:brief。
## 关键规则
1. A股收益率不服从正态分布——尖峰肥尾特征显著
2. 负偏度意味着下跌极端值更多——投资者面临左尾风险
3. 峰度>3说明极端收益出现频率高于正态预期
4. 分布假设影响VaR/期权定价等所有风险计算
5. 不同市值股票的分布特征差异大——小盘更尖峰
## 使用示例
### 示例 1: 基本使用
```python
# 调用 skill
result = run_skill({
"param1": "value1",
"param2": "value2"
})
```
### 示例 2: 命令行使用
```bash
python scripts/run_skill.py --input data.json
```

Playbook for creating and editing uCoz landing pages via MCP tools (`templates_tool`, `ftp_tool`, `modules_tool`). Use for tasks such as: "build a landing page", "update the homepage as a landing page", "create a promo page on the homepage", "add a lead form / menu / SEO to the homepage". Homepage: `page_list`, `page_get`; first publish — `page_update` with full `page_tmpl`; HTML edits after generation — `patch_template` (module_id=2, template_id=1), not `update_template`.

Interact with the Paperclip control plane API to manage tasks, coordinate with other agents, and follow company governance. Use when you need to check assignments, update task status, delegate work, post comments, set up or manage routines (recurring scheduled tasks), or call any Paperclip API endpoint. Do NOT use for the actual domain work itself (writing code, research, etc.) — only for Paperclip coordination.
