DeltaB2vroles: 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 \(\Delta\in\textbf{R}^k\).

Usage

DeltaB2vroles_cat3logit(DeltaB)
DeltaB2vroles_ord3logit(DeltaB)

Arguments

DeltaB

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