A S4 class for K-adaptive partitioning for survival data (kaps).
Objects can be created by calls of the form
new("kaps"). The most important slot is
groupID, which is a vector consisting of the information about classified subgroups.
evaluated function call
formula used in the model fitting
data used in the model fitting
information about the classified subgroup
index for the optimal subgroup among the candidate K
test statistic with the worst pair of subgroups for the split set
overall test statistic with K subgroups using the split set
selected pair of subgroups
selected covariate in the model fitting
selected set of cut-off points
minimum number of observations at a subgroup
Bonferroni corrected p-value matrix. The first row means overall p-values and the second one denotes p-values of the worst-pair against K. The column in the matrix describes the order of K.
adjusted overall test statistic by Bootstrapping
adjusted worst-pair test statistic by Bootstrapping
candidate K used in the argument
a list of results about each K
signature(object = "kaps"): Same as the show method without the optional arguments
signature(x = "kaps", K): Same as the print method with the specified number of subgroups K.
signature(x = "kaps", K): Plot an object
signature(object = "kaps"): Predict an object by the estimated cut-off points
signature(object = "kaps"): Summarize an object by survival times for each subgroup
