By Jan Beyersmann

This ebook covers competing hazards and multistate versions, occasionally summarized as occasion historical past research. those versions generalize the research of time to a unmarried occasion (survival research) to analysing the timing of specified terminal occasions (competing hazards) and attainable intermediate occasions (multistate models). either R and multistate tools are promoted with a spotlight on nonparametric methods.

Recall from Chapter 2 that we need to keep track of an individual’s movements over the course of time. 1 denotes the state an individual is in for every point in time, Xt ∈ {0, 1, 2}. 1 The competing risks multistate model P(X0 = 0) = 1. , Xt = 0) as long as neither competing event 1 nor 2 has occurred. The individual moves to state 1 if the event of interest occurs. Likewise, the individual moves to state 2 if the other competing event occurs first. 2) T := inf{t > 0 | Xt = 0}. T is often called survival time or failure time; it can be thought of as a waiting time in the initial state 0.

5). A binomial experiment can be run with the function rbinom. We illustrate this below. 1. R functions for simulating survival times Distribution R function Exponential Weibull Log-normal Gamma Log-logistic rexp rweibull rlnorm rgamma Use exp on rlogis If the cause-specific hazards have been specified in such a way that a convenience function is not available, general simulation techniques will be useful. , the textbooks by Morgan (1984) and Ripley (1987); see also Rizzo (2007, Chapter 3) for an introduction to this topic using R.

20) where ‘Past’ now means knowledge about all failure, truncation, or censoring events before t. 20) states that the probability of observing an event in dt is 0, if the individual is not at risk just before t. However, if the individual is at risk, an event that happens in dt will be observed; such an event occurs with probability α(t) dt. 21) now also accounts for left-truncation. An individual is only ‘at risk’ right after the time L of study entry. 14) 22 2 An informal introduction to hazard-based analyses K A(t) = k=1 number of individuals observed to fail at tk , number of individuals at risk just prior to tk t of the cumulative hazard A(t) = 0 α(u) du is straightforwardly adapted to data subject to both left-truncation and right-censoring.
