DeltaB2vroles: Identification of roles of vertices in non-degenerate cases

In plot3logit: Ternary Plots for Trinomial Regression Models

Identification of roles of vertices in non-degenerate cases

Description

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

Usage

DeltaB2vroles_cat3logit(DeltaB)

DeltaB2vroles_ord3logit(DeltaB)

Arguments

DeltaB

either a matrix Δ^TB\in\textbf{R}^{1\times 2} or a vector of length 2, if the model is categorical; otherwise a matrix Δ^TB\in\textbf{R}^{1\times 1} or a numeric, if the model is ordinal.

Value

Named list of three components:

vo	coordinates of vertex where the field originates from.
vt	coordinates of transition vertex.
vs	coordinates of vertex where the field is directed to.

Examples

plot3logit:::DeltaB2vroles_cat3logit(c(0.3, 0.7))
