fourD

Data from the placebo group of the 4D study. This study aimed at
 comparing atorvastatin to placebo for patients with type 2 diabetes
 and receiving hemodialysis in terms of cariovascular events. The
 primary endpoint was a composite of
 death from cardiac causes, stroke and non-fatal myocardial infarction.
 Competing event was death from other causes.

The etm (empirical transition matrix) package permits to estimate the matrix of transition probabilities for any time-inhomogeneous multi-state model with finite state space using the Aalen-Johansen estimator. Functions for data preparation and for displaying are also included (Allignol et al., 2011 <doi:10.18637/jss.v038.i04>). Functionals of the Aalen-Johansen estimator, e.g., excess length-of-stay in an intermediate state, can also be computed (Allignol et al. 2011 <doi:10.1007/s00180-010-0200-x>).
