Description: Provides methods for correcting heaping (digit preference)
        in survey data at the individual record level. Age heaping,
        where respondents disproportionately report ages ending in 0 or
        5, is a common phenomenon that can distort demographic
        analyses. Unlike traditional smoothing methods that only
        correct aggregated statistics, this package corrects individual
        values by replacing a calculated proportion of heaped
        observations with draws from fitted truncated distributions
        (log-normal, normal, or uniform). Supports 5-year and 10-year
        heaping patterns, single heap correction, survey weights, and
        optional covariate-conditional (model-based) correction via
        quantile regression forests or linear models to preserve
        relationships. A multiple-imputation wrapper repeats the
        correction to propagate the added uncertainty into downstream
        inference.
