Data Analysis Skill

功能描述

对结构化数据进行统计分析，自动检测异常值，计算相关性，并提供可视化建议。

适用场景:

• 数据探索性分析 (EDA)
• 业务指标分析
• 异常检测
• 报表生成

使用示例

输入:

{
  "data": [
    {"date": "2024-01-01", "revenue": 1000, "users": 50},
    {"date": "2024-01-02", "revenue": 1200, "users": 55},
    {"date": "2024-01-03", "revenue": 950, "users": 48},
    {"date": "2024-01-04", "revenue": 1500, "users": 70},
    {"date": "2024-01-05", "revenue": 1100, "users": 52}
  ],
  "columns": ["revenue", "users"],
  "analysis_types": ["descriptive", "correlation", "outliers"]
}

输出:

{
  "statistics": {
    "revenue": {
      "count": 5,
      "mean": 1150,
      "std": 202.48,
      "min": 950,
      "max": 1500,
      "median": 1100
    },
    "users": {
      "count": 5,
      "mean": 55,
      "std": 8.37,
      "min": 48,
      "max": 70,
      "median": 52
    }
  },
  "correlations": {
    "revenue_users": {
      "coefficient": 0.96,
      "interpretation": "strong_positive"
    }
  },
  "outliers": [
    {"column": "users", "value": 70, "index": 3, "z_score": 1.79}
  ],
  "visualization_suggestions": [
    {"type": "line_chart", "columns": ["date", "revenue"], "reason": "时序数据适合折线图"},
    {"type": "scatter_plot", "columns": ["users", "revenue"], "reason": "强相关性适合散点图"}
  ],
  "insights": [
    "revenue 与 users 呈强正相关 (r=0.96)",
    "2024-01-04 的 users 值 (70) 偏高，可能为异常值或特殊事件"
  ]
}

注意事项

• 数据量限制 10000 条记录
• 仅支持数值型列的统计分析
• 相关性分析需要至少 2 列数值数据
• 异常值检测基于 Z-score (|Z| > 1.5 标记为潜在异常)
