DeltaB2vroles

DeltaB2vroles_cat3logit

DeltaB2vroles_ord3logit

<code>DeltaB2vroles_cat3logit</code> and <code>DeltaB2vroles_ord3logit</code> identify
(in a categorical and an ordinal model respectively)
the role of vertices of a field associated to a change in
covariate values \(\Delta\in\textbf{R}^k\).

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>.
