This book provides an introduction to multistate event history analysis. It is an extension of
survival analysis in which a single terminal event (endpoint) is considered and the
time-to-event is studied. Multistate models focus on life histories or trajectories
conceptualized as sequences of states and sequences of transitions between states. Life
histories are modeled as realizations of continuous-time Markov processes. The model parameters
transition rates are estimated from data on event counts and populations at risk using the
statistical theory of counting processes. The Comprehensive R Network Archive (CRAN) includes
several packages for multistate modeling. This book is about Biograph. The package is designed
to (a) enhance exploratory analysis of life histories and (b) make multistate modeling
accessible. The package incorporates utilities that connect to several packages for multistate
modeling including survival eha Epi mvna
