## Commands

Run via: `bash scripts/abtest.sh <command> [args...]`

| Command      | Description                    |
|--------------|--------------------------------|
| calculate    | 计算两组的统计显著性             |
| sample       | 计算所需最小样本量               |
| significance | 检验p值和置信区间                |
| duration     | 预估实验所需天数                 |
| report       | 生成完整A/B测试报告              |
| bayesian     | 贝叶斯方法分析胜率               |

## Usage Examples

```bash
# 计算显著性（访客数 转化数）
bash scripts/abtest.sh calculate 1000 50 1000 65

# 计算样本量（基线转化率 最小可检测提升 显著性水平）
bash scripts/abtest.sh sample 0.05 0.02 0.95

# 预估实验时长（日均流量 所需样本量）
bash scripts/abtest.sh duration 5000 16000

# 贝叶斯分析
bash scripts/abtest.sh bayesian 1000 50 1000 65

# 生成报告
bash scripts/abtest.sh report 1000 50 1000 65 "按钮颜色测试"
```
