05 regression interpreter

Skill lianxhcn/PXa2026a/skills/core/05-regression-interpreter

Use this skill when reading, interpreting, or writing up regression results. Given a regression table and variable definitions, it explains each coefficient in plain language with correct direction, magnitude and units; reads log-level, log-log and standardized coefficients correctly (semi-elasticity / elasticity / standard-deviation); checks whether a results write-up overstates correlation as causation and rewrites causal wording ("causes/raises/improves") into comparison/conditional wording ("is associated with / higher / after controlling for"); distinguishes statistical from economic significance; and adds outline (**#) comments to bare regression do-files. Emphasizes comparison-not-effect framing and human review; never fabricates coefficients, data, or results.From its SKILL.md

regression-interpreter(回归结果解读员)

会跑回归之后,最琐碎、也最容易出错的一步是把系数写成人话、且不写过头。这个技能帮你把一张回归表解读成准确的自然语言,核对对数/标准化系数的读法,并守住「相关不等于因果」这道护栏。判断权始终在你手里——AI 起草,你回到变量定义和数据核对。对应第 4 讲「AI 协作」的四项训练。

何时用

  • 拿到一张回归表,想快速、准确地把核心系数解释成人话;
  • 因变量或自变量取过对数、做过标准化,拿不准系数该按百分比、弹性还是标准差来读;
  • 写完结果说明,想检查有没有把「相关」写成「导致 / 提升 / 影响」;
  • 分不清「统计显著」与「经济显著」,想说清一个系数在现实里到底多大;
  • 有一段光秃秃的回归 do 代码,想加上分层大纲注释、方便课堂导航与复看。

使用方式(提示词)

逐个解释核心系数

你是一位计量经济学助教。下面是一张回归表和变量定义。请逐个解释【核心系数】:(1) 方向、大小和单位;(2) 若因变量/自变量取了对数,按半弹性/弹性正确解读;(3) 用「比较」而非「因果」的措辞;(4) 每个系数一句话,通俗但准确。 【变量定义】… 【回归表】<粘贴 esttab 输出>

检查相关 vs 因果

请审查下面这段实证结果表述,找出把【相关关系】写成【因果关系】的地方。对每一处:(1) 指出是哪个词(如"导致""提升""使得");(2) 说明为何超出回归能支持的范围;(3) 给出「比较/条件」措辞的改写版本。不要改动数字与结论强度以外的内容。 【待审段落】<粘贴>

核对对数、标准化的系数读法

下面是变量字典和我对系数的解读草稿。请核对解读与变量【变换方式】是否一致:因变量为 ln(·)→按百分比/半弹性读;两端都是 ln(·)→按弹性读;变量标准化→按标准差读。指出不一致处并改正。 【变量字典】… 【我的解读草稿】<粘贴>

回归代码加注释版

请为下面这段 Stata 回归代码加注释:(1) 用 **# / **## 多级大纲注释标出每个分析步骤;(2) 关键命令后加一句行内注释,说明在做什么、为什么;(3) 不改动代码逻辑。 【原始代码】<粘贴 do 代码>

输出约定

  • 系数解读必须说清方向、大小、单位,并按变换方式(水平/对数/标准化)给正确读法;
  • 一律用「比较/条件」措辞(相关、更高、在控制…之后),不下因果结论,除非用户另给识别策略;
  • 区分统计显著(星号、$p$ 值)与经济显著(用实际单位说清效应多大);
  • 加注释时不得顺手改动设定(控制变量、标准误选项等);
  • 一切以用户提供的回归表、变量定义、代码为准,不编造系数、不虚构数据与结论;拿不准处显式标出。

最小使用示例

用 regression-interpreter 帮我解释这张表:因变量 lwage=ln(时薪),自变量 educ=受教育年限,educ 系数 0.109、括号 0.014、三颗星。这个系数怎么读?能说"多读一年书让工资涨 11%"吗?

人工检查清单

  • AI 给的每一句解读,回到变量定义与数据处理代码核对——尤其对数系数是否被当成绝对值、百分比有没有搞反;
  • 因果措辞审查可能矫枉过正,把本就恰当的表述也标成问题,由你判断;
  • 变换方式以你的代码为准,别让 AI 凭变量名猜;
  • AI 辅助、不替代判断:能否下因果结论,取决于识别策略而非回归系数本身,最终由你把关。
