Plot a scatter plot, where the values of rho are on the x axis and the corresponding sums of the squared residuals obtained by a grid search for rho are on the y axis. Estimations that did not converge are marked with red.
Note that this method can be applied
only if the model was estimated by a grid search for rho,
i.e.\ cesEst
was called with argument rho
set to a vector of more than one values for rho.
