Description: Design and evaluate choice-based conjoint survey
        experiments. Generate a variety of survey designs, including
        random designs, frequency-based designs, and D-optimal designs,
        as well as "labeled" designs (also known as
        "alternative-specific designs"), designs with "no choice"
        options, and designs with dominant alternatives removed.
        Conveniently inspect and compare designs using a variety of
        metrics, including design balance, overlap, and D-error, and
        simulate choice data for a survey design either randomly or
        according to a utility model defined by user-provided prior
        parameters. Conduct a power analysis for a given survey design
        by estimating the same model on different subsets of the data
        to simulate different sample sizes. Bayesian D-efficient
        designs using the 'cea' and 'modfed' methods are obtained using
        the 'idefix' package by Traets et al (2020)
        <doi:10.18637/jss.v096.i03>. Choice simulation and model
        estimation in power analyses are handled using the 'logitr'
        package by Helveston (2023) <doi:10.18637/jss.v105.i10>.
