Description: Models with skew‑normally distributed and thus asymmetric
        error terms, implementing the methods developed in Badunenko
        and Henderson (2023) "Production analysis with asymmetric
        noise" <doi:10.1007/s11123-023-00680-5>. The package provides
        tools to estimate regression models with skew‑normal error
        terms, allowing both the variance and skewness parameters to be
        heteroskedastic. It also includes a stochastic frontier
        framework that accommodates both i.i.d. and heteroskedastic
        inefficiency terms.
