A list giving information about censored states, their labels in the data and what true states they represent.
The number of distinct values used for censored
observations in the state data supplied to
msm.
A vector of length ncens, giving the labels used
for censored states in the data.
A vector obtained by unlist()ing a list with ncens elements, each giving the set
of true states that an observation with this label could be.
Index into states for the first state
corresponding to each censor, plus an extra
length(states)+1.
