# 数据分析报告
## 1. 数据概览
- 数据量:{len(df)} 行 × {len(df.columns)} 列
- 时间范围:{df['date'].min()} 至 {df['date'].max()}
- 缺失值:{df.isnull().sum().sum()} 个
## 2. 关键指标
- 总销售额:¥{df['sales'].sum():,.2f}
- 平均订单:¥{df['sales'].mean():,.2f}
- 最高订单:¥{df['sales'].max():,.2f}
- 最低订单:¥{df['sales'].min():,.2f}
## 3. 分布特征
- 偏度:{df['sales'].skew():.2f}
- 峰度:{df['sales'].kurt():.2f}
- 标准差:{df['sales'].std():,.2f}
## 4. Top 5 类别
{df.groupby('category')['sales'].sum().sort_values(ascending=False).head().to_markdown()}
## 5. 趋势分析
- 环比增长:{df['sales'].pct_change().mean()*100:.2f}%
- 月均销售额:¥{df.resample('M', on='date')['sales'].sum().mean():,.2f}
## 6. 建议
1. 重点推广 Top 3 类别
2. 优化低转化品类
3. 关注季节性波动
