plot.cusp {cusp} | R Documentation |
This function generates diagnostic graphical displays of fits of a cusp catastrophe model to data obtained with cusp
## S3 method for class 'cusp': plot(x, what = c("all", "bifurcation", "residual", "densities"), ...)
x |
Object returned by cusp |
what |
1-character string giving the type of plot desired. The following values are possible: "all" for a panel plot with all diagnostic plots, "bifurcation" for a plot of the bifurcation surface with estimated control parameter locations superimposed, "residual" for a plot of the residuals against fitted values, "densities" for a plot of density estimates conditioned on the estimated location on the bifurcation surface. |
