This function updates a scoring algorithm using upper and/or lower fences. Using the call stored in the object, the update function declares outlying observatoins based on the QQ plot. k_s is used to set the upper cut-off bound.
plot
(Package: OutlierDC) :
a plot-method for a "OutlierDC" object
This function provides three different results. If the algorithm is score, it draws a normal quantile-quantile plot of the outlying scores. If the algorithm is boxplot, the scatter plot of log survival times against the covariate used is given. Lastly, if the algorithm is residual, it offers a residual plot.
