direct_from_observed_intervals {icmstate} | R Documentation |
Translate observed transition intervals into direct transition intervals
Description
Given observed transition intervals, determine the "worst" (least informative) possible direct transition intervals that could have occurred to form this sample.
Usage
direct_from_observed_intervals(observed_intervals, tmat, gd)
Arguments
observed_intervals |
Output from |
tmat |
A transition matrix as created by |
gd |
A
The true transition time between states is then interval censored between the times. |
Value
A data.frame
with the following named columns
entry_time
:Time of entry into "from" state;
time_from
:Last time subject(id) was seen in state "from";
time_to
:First time subject(id) was seen in state "to";
from
:State from which a transition was observed;
to
:State to which the transition was observed;
id
:Subject identifier;
For right-censored observations, entry_time denotes the first time
seen in the censored state, time_from the last time seen in the censored state,
time_to is Inf
, from the censored state and to is NA
.
