transMatMSM: Define transition matrix for multi-state model.

In markovMSM: Methods for Checking the Markov Condition in Multi-State Survival Data

Define transition matrix for multi-state model.

Description

Define transition matrices for multi-state model. Specific functions for defining such transition matrices are pre-defined for common multi-state models like the competing risks model and the illness-death model.

Usage

transMatMSM(positions, namesStates)

Arguments

positions	List of possible transitions; x[[i]] consists of a vector of state numbers reachable from state i.
namesStates	A character vector containing the names of either the competing risks or the states in the multi-state model specified by the competing risks or illness-death model. names should have the same length as the list x (for transMat), or either K or K+1 (for trans.comprisk), or 3 (for trans.illdeath).

Value

A transition matrix describing the states and transitions in the multi-state model.

Examples

data("ebmt4")
db_wide <- ebmt4
positions<-list(c(2, 3, 5, 6), c(4, 5, 6), c(4, 5, 6), c(5, 6), c(6), c())
namesStates = c("Tx", "Rec", "AE", "Rec+AE", "Rel", "Death")
transMatMSM(positions, namesStates)
