add_confregions_field3logit

Given the confidence level, it computes the confidence regions
the effects for each arrow of the <code>field3logit</code> object.

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>.
