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.
