conjoint-design

What problem does it solve?

Specialized logic for designing conjoint and factorial vignette experiments, enabling researchers to plan and execute rigorous, policy-relevant attribute-based studies.

Core Features & Use Cases

• Attribute architecture guidance: ensure orthogonality, randomization strategy, and valid design constraints.
• Power analysis and estimation: AMCE/MM estimation, interaction considerations, and robust statistical best practices.
• Design variant guidance: choose between paired-choice, rating, and factorial vignette formats; draft pre-analysis plans and regression specifications.
• Use Case: Design a new conjoint study with 5 attributes and 4 levels per attribute, compare design variants, and prepare a preregistered analysis plan.

Quick Start

Specify your attributes and levels, then request a design and power analysis for your conjoint study.
