vcovB2vcovDeltaB

Given the covariance matrix of parameters, it return the covariance
matrix associated to the change in covariate values in the space
of covariantes.

internal

An implementation of the ternary plot for interpreting regression
coefficients of trinomial regression models, as proposed in Santi, Dickson
and Espa (2019) <doi:10.1080/00031305.2018.1442368>. Ternary plots can be
drawn using either 'ggtern' package (based on 'ggplot2') or 'Ternary'
package (based on standard graphics). The package and its features are
illustrated in Santi, Dickson, Espa and Giuliani (2022)
<doi:10.18637/jss.v103.c01>.
