Turns a raw Qualtrics conjoint export into an analysis-ready long-format dataset, covering export settings, identifying the implementation, package or manual wide-to-long reshaping, choice-profile alignment, ratings, reference categories, pilot exclusion, and subgroup merges. Use when the user has a conjoint CSV to clean, reshape, or debug, cannot align choices with profiles, or asks what the data must look like before AMCE estimation. Design goes to conjoint-design, validity review to…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Conjoint Data Cleaning Expert ### 1. Qualtrics Export Settings and Metadata **Export format:** The right export depends on the pipeline. `cjoint::read.qualtrics()` (Method A) hard-errors when choice columns contain text, so export "Use numeric values" for it. `projoint::reshape_projoint()` parses the chosen profile from a label at the end of the outcome string (default `A`/`B`), and manual reshaping benefits from readable labels, so "Use choice text" works for those. When unsure, export both; they differ only in response coding. If working with non-Latin scripts (Chinese, Korean, Arabic), export as XLSX rather than CSV to avoid UTF-8/ANSI encoding issues. On Windows with East Asian locales, `read.csv()` may still require `Sys.setlocale()` to match the file encoding before import (see `?cjoint::read.qualtrics` East Asian Language Support). …

How to install
mdr add scdenney/open-science-skills/conjoint-cleaning@sha256:b5f662d77ac0f9edThe line at the top of this page pins the label git:20261008.697c89f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
