plot_traj | R Documentation |
Function for plotting the cross-validated peeling trajectories/profiles of a sbh
object.
Applies to the pre-selected covariates specified by user and other output statistics of interest
at each iteration of the peeling sequence (inner loop of our PRSP or PRGSP algorithm).

The plot shows peeling trajectories of some box descriptive summary statistics and survival output statistics
as a function of box support (i.e. peeling steps). It plots peeling trajectories of those only covariates that
are used for peeling. It also plots according to the peeling criterion (peelcriterion
) that is used so that
only relevant outputs are plotted. These outputs are: Size (remaining sample size n in the box),
Maximum Event-Free Time (MEFT), Minimum Event-Free Probability (MEFP), Log-Hazard Ratio (LHR), Log-Rank Test (LRT),
and Concordance Error Rate (CER) if peelcriterion
in {"lhr", "lrt", "chs"}, or Group Log-Hazard Ratio (GLHR),
and Group Concordance Error Rate (GCER) if peelcriterion
= "grp".
The range
list includes user-specified ranges of Log-Hazard Ratio (LHR), Log-Rank Test (LRT), and Concordance Error Rate (CER)
if peelcriterion
in {"lhr", "lrt", "chs"}, or Group Log-Hazard Ratio (GLHR), and Group Concordance Error Rate (GCER)
if peelcriterion
= "grp". In the former case, the list should be of the form range = list("lhr"=..., "lrt"=..., "cer"=...)
In the latter case, the list should be of the form range = list("glhr"=..., "gcer"=...)
