tra_ill(state.names = c("0", "1", "2"))
tra_ill_comp(nComp = 2,
     state.names = as.character(seq(0, nComp + 1, 1)))
tra_comp(nComp = 2,
         state.names = as.character(seq(0, nComp)))
tra_surv(state.names = c("0", "1"))

Arguments

state.names

A vector of characters giving the states names

nComp

For the competing risks models, the number of competing events

Details

These functions compute the matrix of possible transitions that is used as argument in, e.g., the etm function. tra_surv is for the usual survival model, tra_comp for the competing risks model, tra_ill for the illness-death model and tra_ill_comp for the illness-death model with competing terminal events. By default, state names are from 0 to ...

Value

A quadratic matrix with TRUE if a transition is possible, FALSE otherwise.
