startvalues

response vector with 0 &lt; z_i &lt; 1.

matrix containing the covariates for the mean submodel. Each column is a different covariate.

matrix containing the covariates for the precision submodel. Each column is a different covariate.

a string containing the link function for the mean.
The possible link functions for the mean are "logit","probit", "cauchit", "cloglog".

link.mean

Function providing initial values for the Expectation-Maximization algorithm.

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 Barreto-Souza, Mayrink and Simas (2020) <arXiv:2003.05157>.
