Test whether the current k corresponds to a stable partition

# S4 method for ConsensusPartition
is_stable_k(object, k, stable_PAC = 0.1, ...)

Arguments

object: A ConsensusPartition-class object.
k: Number of subgroups.
stable_PAC: Cutoff for stable PAC.
...: Pass to suggest_best_k,ConsensusPartition-method.

Details

if 1-PAC for the k is larger than 0.9 (10% ambiguity for the partition), cola marks it as a stable partition.

Value

Logical scalar.

Examples

data(golub_cola)
obj = golub_cola["ATC", "skmeans"]
is_stable_k(obj, k = 2)
#> [1] TRUE
is_stable_k(obj, k = 3)
#> [1] TRUE
