缺失值处理

先量化字段和行级缺失,判断缺失机制及业务含义,再选择删除、常数、统计量或分组插补。修改前说明影响,保留可追溯结果,并在处理后验证缺失率和分布变化。

Tool routing

  1. Use get_schema to identify tables, nullable fields, and candidate columns.
  2. Use profile_data to quantify missingness before any modification.
  3. Use clean_data with the appropriate missing-value operation only when the user intent is clear.
  4. Use query_data after cleaning to verify row counts, remaining nulls, and distribution changes.
