Generate a Stata .do file that compares every subset of optional control variables across parallel instances. The script ranks combinations by the focal variable’s absolute t-statistic, reports the top ten, and fits the highest-ranked model.
Parallel control variable combination search via Stata. Exhaustively searches all subsets of optional controls to find the combination that maximises |t| of the independent variable. Activates when user says: "控制变量搜索", "搜控制变量", "control variable search", "跑控制变量组合", "暴力搜索", "调控制变量".

This skill generates a parallelised Stata .do file that:
tuplesreghdfe (or user-specified command) for each combination across N parallel Stata instancesImportant: This skill only generates the .do file. It does NOT execute it. Tell the user the output path and let them run it in Stata themselves.
Ask the user for the following. Items marked (required) must be provided; others have defaults.
| Parameter | Description | Default |
|---|---|---|
| data file (required) | Full path to the .dta file | -- |
| dependent variable (Y) (required) | Y variable name | -- |
| independent variable (X) (required) | X variable of interest | -- |
| cluster variable (required) | Variable for clustering SE and fixed effects | -- |
| mandatory controls (required) | Controls always included | -- |
| optional controls (required) | Controls to search over (all subsets) | -- |
| N_WORKERS | Number of parallel Stata instances | 8 |
| significance level | Two-tailed alpha | 0.01 |
| model command | Estimation command | reghdfe |
| absorb | Fixed effects specification | absorb(<<CLUSTER>> year) |
| vce | Variance-covariance specification | vce(cluster <<CLUSTER>>) |
| STATA_EXE | Path to Stata executable | E:\Stata\StataMP-64.exe |
tuples generates 32,768+ combinations
and will freeze Stata. If the user provides more than 14, warn them and ask them to reduce or move
some into mandatory controls.<data_dir>\控制变量搜索_并行.do by default, placed next to the data file.After collecting parameters:
C:\Users\Verasuna\.claude\skills\ControlVariable\template.do<<PLACEHOLDERS>> with user-provided values (see table below)<data_dir>\控制变量搜索_并行.doDo not modify any code logic in the template. Only replace placeholders.
<<N_WORKERS>> e.g. 8
<<STATA_EXE>> e.g. E:\Stata\StataMP-64.exe
<<PROJ_DIR>> directory containing the .dta file
<<DATA_FILE>> filename of .dta (just the name, not full path)
<<SIGNIFICANCE>> e.g. 0.01
<<DEP_VAR>> dependent variable (Y)
<<INDEP_VAR>> independent variable (X)
<<MANDATORY_CONTROLS>> space-separated mandatory controls
<<OPTIONAL_CONTROLS>> space-separated optional controls
<<MODEL_CMD>> e.g. reghdfe
<<MODEL_ABSORB>> e.g. absorb(stkcd year)
<<MODEL_VCE>> e.g. vce(cluster stkcd)
<<HEARTBEAT_STALL>> 300
User says: "Y是GTFPEFF8，X是Size，聚类到stkcd，必选控制变量Lev，可选控制变量ROA ROE ATO Cashflow，数据文件是 C:\data\mydata.dta"
Then fill:

Turn a broad research idea into clear, testable questions. Compare familiar and less conventional approaches, structure the selected question around its population and methods, and assess variables, feasibility, and potential theoretical contributions.
Helps build a research framework by comparing theories, mapping relationships between variables, and deriving testable hypotheses. Explores less conventional options, examines weaknesses and competing explanations, and produces diagrams with anticipated reviewer objections.
Clarify the philosophical assumptions behind a research project and check whether they fit the proposed methods. Get a reasoned research stance, draft proposal wording, and guidance for explaining how the researcher's background and values shape the study.
Plan and draft academic papers through specialized agent roles covering literature, arguments, citations, and review. Get chapter guidance, revision roadmaps, Traditional Chinese and English abstracts, and documents formatted as LaTeX, DOCX, PDF, or Markdown.
Turn a detailed outline into a philosophy or interdisciplinary manuscript. Draft chapters with repeated quality reviews, check terminology and arguments across sections, and prepare the manuscript, evaluation reports, abstract, and metadata for submission.
Simulate academic peer review through five reviewer roles tailored to the paper's field. Receive separate critiques, an editorial decision, and a prioritized revision roadmap, or check whether a revised manuscript addresses earlier comments.
