supportHudgens {icmstate} | R Documentation |
Determine the support of the NPMLE for interval censored data.
Description
Given censoring/truncation intervals, find the maxcliques and determine the support of the interval censored problem.
Usage
supportHudgens(intervals, reduction = TRUE, existence = FALSE)
Arguments
intervals |
A data.frame with 3 columns containing half-open intervals (left open, right closed) and an indicator whether the interval results from a censored transition or truncation:
Note that the truncation intervals need to be in the form (N, Inf] with N a numeric value. |
reduction |
Should the support be reduced using Lemma 3 from Hudgens (2005)? This requires checking an extra condition. Default is TRUE. |
existence |
Should the existence of the NPMLE be checked using Theorem 1/Lemma 4 from
Hudgens (2005)? Requires |
Value
-
graph
: Anigraph
object representing the censoring/truncation intervals -
support
: Support estimated from the censoring intervals -
dir_graph
: A directedigraph
object used to determine whether the NPMLE exists in the presence of left-truncation. -
exist_mle
: Logical output indicating whether the NPMLE exists.
