%description
Functions to fit, via Expectation-Maximization (EM) algorithm, the Bessel
and Beta regressions to a data set with a bounded continuous response
variable. The Bessel regression is a new and robust approach proposed in
the literature. The EM version for the well known Beta regression is
another major contribution of this package. See details in the references
Barreto-Souza, Mayrink and Simas (2022) <doi:10.1111/anzs.12354> and
