## What it does

The skill first asks about the outcome, regressors, controls, fixed effects, standard-error clustering, and the desired table format. It then drafts code to load and inspect data, estimate a model, and export results with `esttab` or `outreg2`.

It can use `regress`, `reghdfe`, or `xtreg`, then explain model estimates, assumptions, and diagnostics. You can also ask for alternative specifications and sensitivity checks. Stata 17 or later is required. Tables made with `esttab` need the `estout` package; `reghdfe` is optional for models with many fixed effects. Earlier Stata versions fall short of the stated requirement.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add meleantonio/awesome-econ-ai-stuff --skill stata-regression -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/stata-regression/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/stata-regression/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add meleantonio/awesome-econ-ai-stuff --skill stata-regression -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/stata-regression/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add meleantonio/awesome-econ-ai-stuff --skill stata-regression -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/stata-regression/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install meleantonio/awesome-econ-ai-stuff stata-regression
```

2. **Manually: put the files in place**
- File: `.github/skills/stata-regression/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add meleantonio/awesome-econ-ai-stuff --skill stata-regression -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/meleantonio/awesome-econ-ai-stuff --path _skills/analysis/stata-regression
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/stata-regression/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add meleantonio/awesome-econ-ai-stuff --skill stata-regression -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/meleantonio/awesome-econ-ai-stuff/tree/HEAD/_skills/analysis/stata-regression/SKILL.md

## When to use it
- estimate a linear or nonlinear model in Stata
- apply fixed effects and cluster standard errors
- export results as a LaTeX, Word, or CSV table
- compare alternative model specifications

## Example prompts
- Estimate `y` on `x1` and `x2`, add firm and year fixed effects, and cluster errors by firm.
- Fit a logit model and export the results to LaTeX.
- Compare three model specifications and create a clearly labelled regression table.

# Stata Regression

## Purpose

This skill produces reproducible regression analysis workflows in Stata, including model diagnostics and publication-ready tables using `esttab` or `outreg2`.

## When to Use

- Estimating linear or nonlinear regression models in Stata
- Producing tables for academic papers and reports
- Running robustness checks and alternative specifications

## Instructions

Follow these steps to complete the task:

### Step 1: Understand the Context

Before generating any code, ask the user:

- What is the dependent variable and key regressors?
- What controls and fixed effects are required?
- How should standard errors be clustered?
- What output format is needed (LaTeX, Word, or CSV)?

### Step 2: Generate the Output

Based on the context, generate Stata code that:

1. **Loads and checks the data** - Handle missing values and verify variable types
2. **Runs the requested specification** - Use `regress`, `reghdfe`, or `xtreg` as appropriate
3. **Adds robust or clustered standard errors** - Match the study design
4. **Exports tables** - Use `esttab` or `outreg2` with clear labels

### Step 3: Verify and Explain

After generating output:

- Explain what each model estimates
- Highlight assumptions and diagnostics
- Suggest robustness checks or alternative models

## Example Prompts

- "Run OLS with firm and year fixed effects, clustering by firm"
- "Estimate a logit model and export results to LaTeX"
- "Create a regression table with three specifications"

## Example Output

```stata
* ============================================
* Regression Analysis with Stata
* ============================================

* Load data
use "data.dta", clear

* Summary stats
summarize y x1 x2 x3

* Main regression with clustered SEs
regress y x1 x2 x3, vce(cluster firm_id)
eststo model1

* Alternative specification with fixed effects
reghdfe y x1 x2 x3, absorb(firm_id year) vce(cluster firm_id)
eststo model2

* Export table
esttab model1 model2 using "results/regression_table.tex", replace se label
```

## Requirements

### Software

- Stata 17+

### Packages

- `estout` (for `esttab`)
- `reghdfe` (optional, for high-dimensional fixed effects)

Install with:

```stata
ssc install estout
ssc install reghdfe
```

## Best Practices

1. **Match standard errors to the design** (cluster where treatment varies)
2. **Report all model variants** used in the analysis
3. **Document variable definitions** and transformations

## Common Pitfalls

- Not clustering standard errors at the correct level
- Omitting fixed effects when required by the design
- Exporting tables without clear labels and notes
