Research cases

Inspect the materials, sample and model, execute selected specifications, and compare outputs with the reference. The published example provides two Table IV columns, actual logs, code and a numerical comparison.

Organize a paper into a focused seminar with concepts, research uses and discussion. Inspect the original task and the published 25-slide English presentation.

Obtain public indicators, check measurement and coverage, align countries and years, and inspect data relationships. The example includes public snapshots, executed Python/Stata code, figures and rerun instructions.

Organize questions, methods and evidence for an academic talk. Inspect the published 25-page Chinese Beamer report and download its PDF; source files for this report are not published.

Explore comparisons, counterfactual reasoning and identification conditions through an interactive teaching canvas. Distinguish course-data analysis, hypothetical counterfactuals and the separate simulated exercise.

Find relevant papers and bibliographic information through the official OpenAlex MCP, and organize a reading list with source links.

Compare two regressions on the same 74 observations, checking coefficients, robust SEs and intervals. Inspect actual results and the guide, then download the do-file, CSV, log and figures.

Check titles, author, years and DOIs for two real public records. Separate source identity from support for claims, and download BibTeX, RIS, a checklist and an unfilled reading template.

Compare one estimate and repeated sampling at different sample sizes in a simulated model with known truth. Inspect 1,000 slopes and summaries, and download Python, simulated data and figures.

Hold simulated data and OLS coefficients fixed while comparing conventional and HC1 SEs, intervals and p-values. Inspect independent Python/Stata calculations and download data, code and actual logs.

Compare traces, acceptance and retained states for three proposal scales against one analytic posterior. Download code, 15,000 states and figures, distinguishing finite-chain behavior from convergence claims.

Turn two executed same-sample Stata regressions into an editable Word table. Check coefficients, robust SEs, sample sizes and notes; download DOCX, CSV, code and actual logs.

Inspect invalid fields, exact duplicates and conflicting keys on original simulated tables while retaining missing values and all merge statuses. Download inputs, row audits, cleaned outputs and independent Python/Stata code.
