cusp.bifset: compute normal/symmetry factor borders of bifurcation set of...

In cusp: Cusp-Catastrophe Model Fitting Using Maximum Likelihood

Description

Given bifurcation/splitting factor values this function computes the border values of the normal/symmetry factor for the bifurcation set of the cusp catastrophe.

Usage

cusp.bifset(beta)

Arguments

beta	values of the bifurcation/splitting factor at which the border values of the normal/symmetry factor is computed

Value

Matrix with columns named beta, alpha.l, alpha.u. The latter two columns give respectively the lower and upper border values of the normal/symmetry factor. Negative values of beta give NaN values for the normal factor.
