projoint_results

Internal constructor for <code>projoint_results</code> objects. 
A <code>projoint_results</code> stores the outputs of a conjoint analysis,
including estimated effects and metadata about the analysis settings.
It is normally generated by <code>projoint</code> and not called directly.

internal

Provides tools for analyzing data generated from conjoint survey experiments, a method widely used in the social sciences for studying multidimensional preferences. The package implements estimation of marginal means (MMs) and average marginal component effects (AMCEs), with corrections for measurement error. Methods include profile-level and choice-level estimators, bias correction using intra-respondent reliability (IRR), and visualization utilities. For details on the methodology, see Clayton, Horiuchi, Kaufman, King, and Komisarchik (2025) <https://gking.harvard.edu/conjointE>.
