Description: Provides pseudo-weighted estimates of means and
    prevalences for finite population inference from nonprobability
    samples using auxiliary information from one or multiple probability
    reference surveys. The package supports estimation with multiple
    reference surveys, allowing auxiliary information to be combined
    when no single survey contains all variables relevant to
    participation. Optional cumulative precalibration can be applied to
    align weighted totals of shared variables across surveys. Methods
    are based on the generalized estimating equations framework of
    Landsman et al. (2026) <doi:10.1002/sim.70403> for correcting
    participation bias. For a single reference survey, the package
    implements the raking ratio calibration method and includes the
    adjusted logistic propensity (ALP) method of Wang, Valliant, and Li
    (2021) <doi:10.1002/sim.9122>, as well as the Chen-Li-Wu (CLW)
    method of Chen, Li, and Wu (2020) <doi:10.1080/01621459.2019.1677241>.
    Analytic variance estimation uses Taylor linearization and accounts
    for complex sampling designs in the reference surveys via integration
    with the 'survey' package.
