Estimation of Transition Probabilities for the Illness-Death Model

Description

Estimation of transition probabilities for the illness-death model. Both the Aalen-Johansen estimator for a Markov model and a novel non-Markovian estimator by de Uña-Álvarez and Meira-Machado (2015) <doi:10.1111/biom.12288>, see also Balboa and de Uña-Álvarez (2018) <doi:10.18637/jss.v083.i10>, are included.

Examples

data(colonTP)

# create a TPidm object with s = 0, t = "last" (default),
# CI = TRUE (default) and method = "AJ":
aj0ci <- TPidm(colonTP, s = 0, method = "AJ")
summary(aj0ci) # summarizing the results
plot(aj0ci) # plotting all occupation probabilities
